ATi 4870 in boot camp?

The fact that the Mac Pro is getting the 3870 at the same time as windows gets the 4870 is a joke, however, I was wondering if it would be possible to leave in the 2600 for OSX and throw in a 4870 to use in boot camp Windows? If this is a feasible option then I would be interested in upgrading back to Mac.

Agreed...
I had two 8800GT's in my MacPro (3.0GHz) which worked fine (individually) in both OSX, and Vista64. (Ubuntu's X11 config is another story!)
But now, I have an XFX GTX280 in slot 1 and an one of the 8800GTs in slot 2.
To do this, I had to rewire one of the supplied 8800GT PCIe power connectors, because they use a smaller, scaled-down version of the 6-pin PCIe cable connector that connects to the MP mobo. I showed my PC buddy who builds PC Audio workstations for a living, and he's never seem them before...
Gee, thanx Apple for not using standard modular PSU PCIe connectors on the MP mobo!!
Keeping the scaled-down connector end, (obviously) I wired onto it a 6+2 PCIe connector to drive the GTX280 as it requires (like the new 4870) 1 x 6-pin and also 1x8-pin PCIe power connectors. So both the MP PCIe power connectors coming from the mobo are powering the GTX280.
This site is an excellent description of the 6+2 PCIe connector that included power diagrams for the 6, 6+2 and 8 pin PCIe Connectors. Infact if you need to make your own "anything" power cable, this site is I keep coming back to...
http://www.playtool.com/pages/psucon...onnectors.html
Why use a 6+2 pin PCIe power connector and not the 8-pin PCIe connector? Cos now I can revert back to having 2x 6-pin connectors anytime I need to put the 2nd 8800GT back in...
My rewiring wasn't pretty, but it gets the job done. So much for the MP having a nice cable free mobo feel about it...
So, Given that I used up the 2 6-pin cables from the MP's mobo, to get power to the 8800GT, I used the XFX GTX280's supplied 6-pin PCIe to 2-Molex connector and sourced power from the 2 optical molexes that power the optical drives.
Consequently, I don't have the optical drive connected at the moment, but I want to do more testing before I use a molex splitter.
Given that the 2 video cards are never used for 3D gaming simultaneously, I'm already confident the MP PSU is coping well with the power requirements. (1200W is what I've read elsewhere!! )
So, Assuming no OSX drivers for the 4870. (any word of OSX drivers for the 4870 yet?)
If one were to install one 4870 in a MP for Windows, some splicing-and-dicing would be needed (like above) if you wanted to use a 3870/4870 as well for OSX.
Note: Holding down option to choose what to boot from via EFI is not possible unless I have the 8800GT installed. The GTX280 is not displaying anything on screen when in EFI.
With my DELL 24" monitor connected to the GTX280, the Dell's LED on the front is not aware/powering-up/receiving-signal etc etc either.
The GTX280 was bought for an Nvidia mobo that can do 3-way SLI so I'm still hoping that 2x 3870s in crossfire is not going to be the fastest and best option for Windows gaming on a MacPro, AND while still have the use of the video cards in OSX.

White screen of death and computer halts with ATI 4870 in Boot Camp

Hi!
I have just received the ATI Radeon 4870 for my Mac Pro (Early 2008)and have upgraded my Leopard to 10.5.7 and works fine on the Mac side. When I reboot and hold the command key I can see my MAC and my BOOT CAMP 2 options as always before. When I click on boot camp I get a white screen with a black frome around it and there is NO hard disk activity and nothing happens no matter how long I leave the computer alone. Before I had no problem booting into my boot camp loaded with vista 64 bit. I have another partition with parallels and that is fine but not this boot camp partition.
I am using ONLY this card in the system. I removed the NVIDIA card.
ALso I tried putting in my Vista 64bit DvD into the drive and rem=booting and see the option when hold the option key to go into MAC,WINDOWS,DVD.... When I select DvD and computer adjust to work in a windows enviroment again the system halts. SO I believe it has nothing whatsoever to to do with drivers inside Vista. It would have to be something that needs upgrading for bootcamp to allow for this video card to work on Bootcamp?
Again I have the latest updates of the OS.
Any suggestions?
Thanks for all your time!

CorkyO recommended what I would do: install old card, uninstall any graphics drivers and delete them, and use Driver Sweeper as well. So that there is nothing there.
If you have a raw unformatted drive, pull everything else and leave that in.... as if it was a PC and starting for the first time.
Don't use Boot Camp Assistant.
Don't put Windows on the same drive as OS X.
Do try Windows 7.7100 RC 64-bit.
Apple has not posted a link to graphics drivers since early 2008.
http://support.apple.com/kb/TS1442 - "Not found" and WAY out of date (167.xx) which would be foolish and obviously would not support Vista or 4870.
I would pull the Vista drive for another reason, too, so you can start fresh and import or access the files on it later.
Vista is sensitive to the presence and drive position of where the drive and OS was, the master boot record and such which I confess to not fully understanding.
Which is another reason to install Windows with no other hard drives present.
You keep saying you used COMMAND rather than OPTION key to restart into Windows, so figure typo/slip.
I would RESET SMC and ZAP PRAM/NVRAM. Force the device tree to get rebuilt. And that is important to OS X - suppose to do so but the G5s it never worked properly on its own.
There is a reason why people that play with graphics cards and drivers use Driver Sweeper, it works, and it is essential at times.
Early boot is under the control of EFI. I don't know what if anything Apple does (I don't trust the firmware updates that were suppose to provide better Windows compatibility only to learn it was mostly for XP and not Vista, and that it added a full 30 seconds to my boot routine into Windows - where EFI + Boot Camp does make Windows think there is a traditional BIOS.... my best summary guess.
Work with the only factual symptom: pulling one card and putting in 2nd is causing a problem.

ATI X1900XT and Boot Camp 1.3

I've just upgraded to an ATI X1900 XT connected to two Dell 24" LCDs. When booting into Windows XP using Boot Camp Beta 1.3 the screens flicker badly and the second screen shows only about ont third the width until the Windows 'Welcome' page appears, after the drivers are loaded.
When I had the nVidia 7300GT in both screens mirroed normal quality (stretched 640x480 8bit) video during boot until the drivers loaded.
Is this normal with the ATI? It doesn't look right but works OK once Windows has booted and runs both monitors at 1920x1200 32bit colour.
When booting into Mac OSX the card works normally.
Has anyone experienced this 'fault'.
I've installed a clean version of Boot Camp and Windows but nothing has changed the fault.

It's certainly the case that the drivers haven't loaded, I uderstand that. What I don't understand is why the nVidia card could operate both monitors during the intial load, prior to the Windows drivers loading, and display correctly on both monitors but the ATI isn't doing this.
As I said I suspect the card isn't locing into an accepted resfresh rate for the monitors until the drivers are loaded.
I'm not inclined to change the Windows drivers to Catalyst as the cards use EFI firmware and I'm not sure about the compatibility with Boot Camp. Regardless, once loaded the drivers work. It's during boot up, only into Windows XP, the card is acting weirdly.
The other weird anomally is that it requires the monitors to be connected in reverse order for Windows. The main monitor is connected to the 2nd DVI port and the secondary monitor to the 1st DVI port. If not when Windows finishes booting it indicates my right hand monitor is monitor 1 (with the Windows menus/start etc) and the left is monitor 2.
When booted into OSX the monitors are detected correctly.
By changing them and then rearranging the monitor order in OSX I can work around this but it is seriusly weird.

Boot Camp, Vista Ultimate x64 SP1, 2009 Mac Pro Quad 2.93, ATI 4870 HD

Hello All,
I’ve run into a problem installing Boot Camp with Vista Ultimate x64 SP1 on my early 2009 Mac Pro Quad 2.93 with Apple’s ATI Radeon 4870 HD (the one with one DVI and one mini-display). I followed the instructions from the Boot Camp Installation and Setup Guide, and everything was going great until I hit page 12 of the Guide (Step 3). The Boot Camp drivers installed without error, and prompted me to reboot. Upon rebooting onto the newly installed Vista x64 partition, the screen went black after the chkdsk screen appeared. I can boot into Vista safe mode, but booting into Vista normally results in the black screen. On a hunch, while in safe mode, I uninstalled the ATI video drivers installed by Boot Camp. I was then able to boot Vista normally, but only with the standard VGA adapter. Then I tried installing the latest 9.4 ATI drivers from the chipset vendor, AMD, http://game.amd.com/us-en/drivers_catalyst.aspx. Booting normally after the ATI chipset drivers were installed left me with a mostly black screen, and a few swizzles of horizontal color, but not enough to make out any sort of image. Once again, I was able to boot normally by first booting into safe mode and then uninstalling the ATI driver, leaving me with the standard VGA driver.
The displays I have tried so far are 1) Apple Cinema HD 23”, and 2) Apple Cinema 20”. Also, I have tried all 6 permutations with the ports on the Apple version of the ATI Radeon 4870 HD with both displays (using the mini-display to DVI adapter), 2 permutations with both displays, and 4 permutations with single displays. All permutations result in the same black screen after installing Boot Camp drivers.
Am I missing something? It seems to me that there is a display driver that needs to come from Apple that will work with the Apple version of the ATI Radeon 4870 HD in Vista Ultimate x64 SP1 attached to an Apple display. I’ve installed Vista Ultimate x64 SP1 and many other operating systems in the past 27 years of working with computers, and typically with video cards I’ve had to get the drivers from the vendor that shipped the card, not the chipset vendor. Sure, occasionally the opposite is true, and I don’t mind spending a few days to figure out what works best for me as long as I believe I am making progress.
Has anyone else run into this problem with his or her early 2009 Mac Pro Quad 2.93 with Apple’s ATI Radeon 4870 HD? I’m posting this in the Boot Camp forum as I think this problem is rooted in the Boot Camp drivers, specifically for the Apple ATI Radeon 4870 HD. Please let me know if I should post elsewhere.

You are the second person I think I've seen with trouble using Mac Pro and ATI drivers (other was on Mac Pro forum).
When updating graphics, there are extra steps that insure you get the best working drivers.
I've always found Apple to be behind the curve on Windows support. Drivers that come with a card from the vendor ususally means ATI or Nvidia, and even then, you go to the web and download and install the latest tested / beta / qualified drivers. Some people try a variety of driver versions to find the one that works best.
Apple has not been updating Boot Camp drivers for Late 2008 and on Macs. Boot Camp 2.1 is now over a year old. What is on your OEM Leopard DVD is the only drivers I would use - if at all! try without is what some do, and then see if you can selectively install. Under Windows 7, I don't need or install, and now with the RC/7077 version of 7, Microsoft 'blocks' installing Apple Boot Camp drivers as known to cause problems.
If it ain't broke, don't fix it. Unistall the various Apple services, drivers, startup items that you can live without or until you narrow it down. iTunes 8.1+ in Windows can break and prevent ability to even use optical drives and devices for instance.
Some tips for upgrading drivers, one from eVGA forum but should translate.

Upgraded to ATI 4870 on Mac Pro and cant enter Boot Camp

Hi!

Thanks for all your time!

I guess you can't boot Safe Mode.
I would have uninstalled the graphics drivers first, as part of preparing to swap cards. Assume you had.... before this and the proper ATI (or Nvidia) drivers. Put back in the original card.... or are you trying to use both? Again, not clear from your comments.
You can't use ATI and Nvidia in Windows concurrently, don't know why but seems to be rule that they won't be compatible.
You have another - physical - native Windows partition? or a Parallels VM that is not using a native (Boot Camp) partition, which works.

Dual monitor not working under Boot Camp on Mac Pro ATI HD 2600 XT

Recently got a brand new Mac Pro with ATI Radeon HD 2600 XT graphics card.
On the Mac side (Leopard), everything works perfectly: my second monitor (a plasma screen connected with HDMI to the second DVI of the ATI card via HDMI/DVI adapter) is fully recognized and it works as an extended desktop or in Mirroring mode.
Under Boot Camp (Windows XP Pro) however, NOTHING: the second monitor always appears in the display properties, but it is grayed out (inactive), and when I try to activate it, it switches back to being grayed out immediately and nothing gets displayed on it.
After reading all the posts I can find on the topic, I tried the following (in pretty much every possible combination - Thank god for WinClone that allows me to restore the Boot Camp basic install image without having to reinstall Windows from scratch every time):
a) Bootcamp 2.0 (installed by default by Bootcamp assistant)
b) Update to Bootcamp 2.1
1) Windows XP Pro SP2c vanilla install (from my Windows XP pro install disk)
2) Update to Windows XP SP3 (I tried with and without BC 2.1: both worked -> BC 2.1 didn't seem to be required for SP3 - maybe because this is a mac pro and not a MB or MBP)
i) ATI drivers installed by default by Boot Camp assistant (BC 2.0) or by BC 2.1
ii) Latest ATI drivers found on ATI web site specifically under Boot Camp / Mac Pro.
Note: Interestingly, the catalyst installer worked ok (provided .NET framework 2.0 is installed though), but it seems that the Radeon BootCamp/Mac Pro driver set itself from ATI's web site does NOT include a driver for the HD 2600 XT - so when I install this driver set, it tells me that no compatible hardware was found...
iii) Latest ATI drivers found under Windows XP (these did include one driver specifically for the Radeon HD 2600 XT)
NOTHING seems to work. I read posts (most of the from late last year) about ATI Catalyst utility showing a 3rd monitor at some point, but I never got any 3rd monitor showing in any of my many many trials with Catalyst. I have yet to get a single image appear on my plasma under Bootcamp Windows. I don't believe its the hardware because everything works great on the max OS X side.
I am actually considering switching to an NVidia 8800 GT just to get the dual screen to work under BootCamp/Windows XP because I really need it and I read everywhere that drivers for NVidia are far better than ATI ones.
Any advice? What should I try next before getting an 8800 ?
Is there a diagnostic utility that I can use to test my config including the GC?
Thanks!

Hi there aside from my laptop I have an iMac 20" with the same HD 2600 XT card. I recently installed the Catalyst 8.6 driver by using a driver mod from driverheaven, I use Vista 32. By installing it this way I got boosted performance and many issues with the bootcamp drivers were fixed. As you may already know the ATI drivers do not install on bootcamped macs usually but the mod tool fixes this. Its unofficial so do so at your own risk but try it out and see if you get the second monitor if not just rollback. Hope this helps and I didn't want to say too much about the 8.6 driver mod because it may not be allowed here but google will provide any answers.

ATI driver installation issue with Windows Vista on Boot Camp (new iMac)

I've just purchased a new 20" iMac with Core 2 Duo 2.4GHz.
Then I installed Windows Vista Ultimate on a Boot Camp partition.
Vista installation was eventless and worked nicely.
Now the problem has begun...
I downloaded the latest ATI graphic card driver (Catalyst 7.7 for Vista 32) from the ATI website. The Catalyst software did not recognize the graphic card and installed nothing. I still have generic Microsoft standard VGA video adapter, which keeps me from playing any recent 3D games...
Someone please help me on this so that I can start playing Oblivion...

Hi and welcome to Discussions,
I still have to find a verification for this, but:
Aplle has up to now always used the Mobility versions of the ATI and NVIDIA graphics chips in the iMacs and MacBooks, MacBooks Pro.
I assume that the in the new imacs, they are also using the Mobility version of the Radeon 2400/2600.
The ATI drivers you can download from the ATI/AMD website are only suitable for the Desktop Radeons, NOT for the Mobility Radeons.
ATI/AMD does not provide drivers for the Mobility Radeons, but are refering to the Manufacturer of the Computer for Drivers, which is Apple.
Sorry to say, but it seems you have to wait for a new BootCamp version which you include Driver support of the new iMacs.
Sorry

Help With boot camp installing on Mac Pro with a ATi Radeon x1900 card

I go throw the boot camp setup with setting my drive and burning the cd drives from mac os... So when I re start the computer and start installing.. My video card is not working... The screen is all chopped and bars running every were, so I can see what Im doing to install vista ... So how do I change this is their some upgrade with the video card and how do I do that
Im using this setup
I have a mac pro 3.0 8 core
ati radeon x1600
using boot camp 1.3
have vista untilamte
Thank You

I don't use Bootcamp/Parallels/Windows but I saw in the Bootcamp forums that someone solved this issue by going to the ATI site and downloading and installing the X1900 drivers for Windows (http://ati.amd.com/support/driver.html). They had to do this while in Windows (which was difficult) do to the garbled screen but managed to suceed. Not sure why they didn't download the trial version of Parallels and do the same thing with an ungarbled screen.

Mac Pro, ATI X1900, Apple Cinema, and Boot Camp

Ok so I finally got Windows to install on to my Mac Pro. This is a long explanation because it includes a lot of information for users who may be having the same problems I had. My problem is at the bottom, but for those of you who are still stuck on the blank screen, READ ON!
Many have users been having problems installing Windows on Mac Pros with the ATI x1900 video card.
For Example, after running boot camp and loading XP the screen would go blank.
To get around this use the DVI to VGA addapter and plug a seperate monitor in, once the computer has finshed installing Windows, then install the drivers.
At this point my graphics card was still not installed correctly. I downloaded the driver off of the ATI website, however I kept recieving errors. So I unpakaged the driver and had the computer find a driver in that folder. Once this was done I went back and installed the remaining software without errors!
Now, currently I am still having to use a second monitor because my HD 23 inch was just showing a blank screen. To fix this I,
1. Installed the video card controller from the ATI website for the ATI X1900
2. Opened advanced settings and supported HD 1080i
3. Connected my HD monitor in the second DVI slot
4.exteneded onto that monitor
5. Switched that monitor to primary
And Perfect! It works
However, this is where problems began to arise. After customizing everything to my taste, I ran a test within this same program which sets all of your graphics card's settings to the optimal setting. I walked away because it was taking a long time, and when i came back my screen was totally messed up. It looked as if the settings had been changed and it had been moved up. With the top of the windows screen down where the dock is supposed to be, and then the dock right above that. I cannot correct this and it is extremely frustrating!
Is there anyway for me to correct this? It is normal in Mac Mode, but in XP i can't correct it. It just seems like there is one problem after another!

so did you install the bootcamp drivers?
because i had no luck with ati's drivers from their web site but apples drivers worked fine.

Mac Pro/ Leopard/ Boot Camp/ XP and 2 ATI Radeon XT1900 ????

I recently went surfaced from a hardware nightmare with my Mac Pro. I need 4 monitors on the XP pro/ boot camp side and was unble to do so using an added ATI XT1900 to my Mac Pro. The drivers would not successfully load. Also the added card buggered the original card. After uninstall and some trouble shooting I was able to get back to a functional configuration with 1 card.
Now that Leopard is out with the new boot camp.... does anyone have experience (successful) with 2 video cards (ATI radeon xt1900) in boot camp/ XP pro??? I dont want to go through me last experience as my job depends on the XP/ boot camp working.
Thanks in advance for your help.
Dan

Correct me if i'm wrong, but the original poster didn't ask or mention anything about Crossfire. (though as a side note, I have read that some people have sucessfully got their 7300gt's into SLI by purchasing a special dongle and downloading a hacked driver.)
And as to whether a user would need two or more monitors for their needs is completely up to the them if it fits their needs, the way i see it the term 'waste' is subjective depending on the user and his/her needs.

WinXP SP3 and Boot Camp 2.1 | Win BSOD ATI card not correct!

Configuration:
Loaded and OEM WinXP SP3 on an iMac with Boot Camp V2.0. All worked correctly.
Immediately after Boot Camp 2.0 completed installed Boot Camp V2.1. All worked correctly.
Problem:
Working in Windows the OS triggered a BSOD (Blue Screen of Death) after the OS was up for approximately 10 minutes. This was a repeatable problem.
Investigation:
Downloaded Windows DeBug utility to analyze the crash dump files from the BSODs. For reference on how to read the Windows dmp files and how to use Windows DeBug utility see the following link.
http://www.networkworld.com/news/2005/041105-windows-crash.html
Determined that the fault was caused by a driver file ati2mtag.sys.
Checked the version with the latest availble from the manufacturer ATI. It was the most recent version
Analysis:
In Windows right click on My Computer, go to Properties.
Go to the Hardware tab in Properties, and then to the Device Manager, drop down the Display adapters. The model shown was a Mobility Radeon HD 2600 XT!
This is WRONG, the video card in this iMAC is a ATI Radeon HD 2600 Pro.
Conclusion:
Windows and or Boot Camp loaded the incorrect video drivers for the video card.
Solution:
1. Download and install Dot Net 2.0 because the ATI driver installer requires this level to install required drivers. The download is available at the following link.
http://www.microsoft.com/downloads/details.aspx?FamilyID=0856EACB-4362-4B0D-8EDD -AAB15C5E04F5&displaylang=en
2. Go to ATI driver support page and download the latest Catalyst driver for 32-bit XP.
http://game.amd.com/us-en/drivers_catalyst.aspx?p=xp/radeonx-xp
3. After download, launch the installer, just proceed with the installer until it gets to the point where it pops up an error message saying that the installer could not find a suitable driver for your hardware.
4. Close out the installer and right click on My Computer, go to Properties.
5. Go to the Hardware tab in Properties, and then to the Device Manager, drop down the Display adapters, and you should see Mobility Radeon HD 2600 XT, this is incorrect.
6. Right click on the video card and choose Update Driver, you will be now see a Hardware Update Wizard.
7. It says Can Windows connect to Windows Update to search for software? Select No, not this time, and click Next... Now you should see What do you want wizard to do? Select Install from a list or specific location (Advanced), and click Next.... On the next page select Don't Search. I will choose the driver to install, click Next....
8. On the lower right corner of the Wizard, Have Disk... Now click Browse and go to C: > ATI > Support > Driver, and select the inf file in there, click Open.
9. Scroll through to locate and then select ATI Radeon HD 2600 Pro, and install that, you might get a message saying this driver isn't certified, ignore it and continue.
10. After completion, reboot.
My system is now running correctly, no more BSOD's!

hmm, is it possible that the same problem of the imac is mine on the macpro with 2 ati 2600 cards?
from where do you know that the recginized xt card is wrong and it must the pro version? cause of the 256mb to 512mb at the offical xt version?
plz take a look at my problem thread:
http://discussions.apple.com/thread.jspa?threadID=1686327
thx alot

Two ATI video cards in Vista 32 with Boot Camp

Hello,
I just installed a second ATI Radeon 1900 video card in my 2007 Mac Pro. It seems to work fine while in OS X, I can adjust and use three different monitors at once. However, while in Vista 32, only two monitors on one card will work and the video is mirrored. I tried adjusting it in the control panel but it could only see one monitor. I also tried to install the ATI catalyst manager but I cannot seem to find the application, it seems to not install correctly. The two screens worked fine before installing another video card of the same model. Is there anything I can do to get all three screens to work correctly?
Thanks for any help

I have used the Expansion Slot Utility to change several different settings. I tried one where the original card was on x16 and the second card was on a x1 or x2, and another attempt where both cards were on x8. For use with OS X it didn't make a huge difference, they all worked fine. However in Vista, I cannot get the cards to work when both are installed. The card will function fine in x8 or x16 while it's on it's own but when the second one is connected no card works well. I have installed catalyst and new drivers, in Vista. When only one card is installed the ati driver works fine and catalyst can control the monitor. With the second card installed the driver doesn't load. I have also updated the firmware with the boot camp firmware ati update.
Thanks for any help or suggestions, I may go back to VGA splitter for Vista.

ATI 6750M issue in Boot Camp

I recently purchased a Mac Book Pro for gaming and work. (15" with 8GB ram, 2.3Ghz with the 1GB ATI 6750M)
I used Boot Camp to install Windows 7 for some of my windows related games. Unfortunately, games like WoW, and other steam games don't seem to take advantage of the ATI 6750M even though the drivers are installed.
I know WoW has a MAC client, but I was hoping to make my Windows install ... My "gaming" environment, where all my games lived.
WoW for example says I don't have a shader compatible card installed. The new FPS Brink seems to run at around 20 FPS.
Any suggestions?

No answers yet, but I saw an update come from Apple today on Boot Camp performance and the Turbo processor.
Maybe this will be taken care of.

Updating an ATI video drivers in Boot Camp with Vista, should it be done?

I use Boot Camp on my Mac Pro for games. I play Age of Conan on Vista on my Mac using Boot Camp. I can't play Conan anymore because it is telling me to update my video drivers but I am worried it will effect the Mac side of the computer. What should I do?

The guide on drivers heaven tells you all you need to know, disable the UAC in vista and reboot. Download the ATI driver package which is now 8.6, extract the package and then cancel the install. Use the mod tool and then navigate to the ATI folder and double click setup. It should run perfectly and all is well, I did it the other day with my iMac which has the ATI Radeon HD 2600 XT chip. The simple way to say what the mod tool does is that it changes the driver to recognise the apple signature on the chip.

IMAC i7 radeon hd 5750 update ati driver boot camp

So basically I have a 2010 iMAC i7 with a radeon
HD 5750 graphics card. Now to my question: I've recently installed win 7 proffesional
Using bootcamp and would like to update the ati driver
to which ever is most recent off AMD website, as I assume doing so
may boost video performance in the games I'm currently playing, as opposed to the
Outdated drivers installed via boot camp.
I however am not sure if I need to uninstall the boot camP video drivers
first, or how to go about doing so as I don't see any on list
Of installed programs. I already know the iMac video card is REALLy Radeon Mobility 5850, not hd 5750
as stated by apple, just need to know if I should uninstall my current video driver in windows 7 before trying to install the most recent mobility 5850 drivers from AmD site, if it's even worth it.

How is this problem resolved...I am having the EXACT same problem???
