"iMac 27" with quad core with an ATI Radeon HD 4850 512MB video processor"

I'm about to order a new iMac 27" quad core with an ATI Radeon HD 4850 512MB video processor.
I'm a long time PC gamer but decided i want to make the full switch to Mac and I have a few questions about the graphics capabilities of this computer.
I game in a clan that plays Battlefield 2 Project Reality.
Will this card handle this game at the high settings and native resolution of the monitor? I also play COD4 and have the same question for that game.
Thanks for your input. I'm sure this will be helpful for all of us and I will share it with my clan of over 100 people strong.

Yeah it plays crysis fine, here is a video of me playing it:

My specs are: Core i7, 8gb of ram and ATI 4850.

IMac w/ ATI Radeon HD 4850 512MB

I'm about to order a new iMac but i have a few questions about the graphics capabilities. I'm a long time PC gamer but decided i want to make the full switch to Mac. Ideally a MacPro would have been my first choice but im not that rich.
I intend to order an iMac with the ATI Radeon HD 4850 512MB. Will this card handle games pretty well? I play world of warcraft and EVE online.
Thanks for your input.

only issue here is that EVE for mac has a graphics bug because of driver issues... I dont know if this applies to the ATI iMacs, but it sure affects my Nvidia iMac. And this is a bug that have been present since EVE was released for mac, and Apple are aware of the problem, but has yet to fix it. So if I ever play EVE for more than background playing or in station use, I always restart into bootcamp, to play EVE there...

New Quad Core 3.2ghz, ATI Radeon HD 5870--pretty noisy fan high pitched?

I just received my new Mac Pro today. I do notice that there is a higher pitched fan noise--I think it is a fan--with this machine. Would like to know if this is normal. I can hear it rev up as I play a video or download a large file. I believe that it is probably the graphic card, but I'm no expert. I live in a very quiet space, so I can hear it in the bedroom next to my living room, where the computer is. I did a little research on the net and saw that under load this card can get pretty noisy, but I do hear this higher pitched sound when not stressing the system, though it is even and stable. I did realize that when I upgraded to the better graphic card there was a risk of a bit more noise and I don't want to be naive, trade it in or have it replaced and end up with a similar noise because they just make this noise normally.
I guess I am asking if this card makes a definite contribution to the machines noise factor.
Otherwise, so far love the machine.
thanks

I would think it's fairly easy to determine if it's the video card fan or not by simply taking off the cover and listening close. The video card is in slot one. You can see the card's fan in there so get up close and listen.
The machine has no problems running with the cover off. It's really not going to overheat. And the video card fan is a plastic "turbine" driven by a small weak motor.
Since you describe the sound as "high pitched" I'm inclined to not think it's the video card fan. On the other hand I suppose it might be if the fan bearing is bad. My original 5870 (it's been replaced) had a bad bearing. But in my case it was either poor lubrication or the bearing itself because the motor couldn't overcome the starting friction (which is why I said the motor is "weak"). My problem manifested itself with the fan not starting most of the time which in turn would cause the card to overheat in about 5 minutes and the machine would go into thermal cutoff. So there is some precedent for bad bearings in these cards.
By the way, when I trouble shooting this problem, I always ran with the cover off so I could keep an eye on the video card fan. If it didn't start up I would just reach in there and give the fan a small "nudge" to get it going. It would then run until the next reboot.

My new iMac 27 i7 quad core (early 2011) is slower than the iMac 21 core duo 3,06 ghz (late 2009).

hello i've just bouth my new imac 27" ( spring 2011) with quad core i7 3,4ghz 4gb ram and 2gb ati radeon graphics..
I've proceded with the migration assistent and just copied my old configurations, programs and datas from the old one ( imac late 2009 27" 8gb ram intel core duo 3,06 ghz, 256mb ati radeon graphics) to the new one...now they are twins with boot lion 10,7,2..what i've just discovered? that the old one is a litttle faster than the new one.
photoshop is opening faster
and more or less all the adobe suite..
is that a joke? how is that possible? i can think that the issue is all about the RAM (4gb new imac, 8gb old imac)..
could someone help me please?
thankyou.

As far as I am aware iMacs do not have upgradeable CPUs.

Quad Core iMac vs. Quad Core Mac Pro?

My old Dual 2.5Ghz PowerMac had a coolant leak and Apple is replacing it with a Quad Core 2.66Ghz Mac Pro with 8 gigs of ram and 1 terabyte hd. Is the new Quad Core iMac a more powerful computer? 2.66Ghz vs. 2.66Ghz - NVIDIA GeForce GT 120 vs. ATI Radeon HD 4850? I'm thinking about not even opening the Mac Pro and putting it and my 24" Dell monitor on eBay. Help!

The iMac still has no PCI Express slots and is limited in the RAM upgrade versatility compared to the Mac Pro. Furthermore with only a single Firewire port, uncompressed video capture to a fast hard drive has to take place to a separate partition of the internal hard drive to ensure uninterrupted capture. On the hand it has an infrared port for the remote that the Mac Pro doesn't have, and an SD slot. The SD slot is good for still digital camera media, if you have an SD compatible camera, and it is good for "sneakernet" of data to other machines with SD slots or SD camera adapters. Many printers have these slots nowadays too. A bootable backup can be made to an SD card.
PCI Express offers SATA cards, and Fiberoptic connector cards for faster hard drive connectivity, as well as faster networking, and faster video and audio interface cards than can be found via Firewire and USB.
Also the Mac Pro can have up to 4 internal SATA hard drives.
So the question is, are you going to miss the expansion capabilities, or not? That should be the deciding factor.

How can I operate multi displays on my Imac 21.5 quad core 2.5 and have each display function independently?

how can I operate multi displays on my Imac 21.5 quad core 2.5 using Lion and have each display function independently?

Below are some converters/adapters to look at. If these look like they may work:
USB 2.0 to HDMI Audio Video 1080P Adapter for Windows and Macbook
Matrox DualHead2Go D2G-A2D-IF (or look here)
These should allow you to run multiple displays in extended display mode. Note that these use HDMI as an output so you would need some additional adapter to conver HDMI to whatever your displays require. Of course these suggestions are all academic if such an adapter doesn't exist.
Update:
I just reread your last post and I am confused. Is it only your TV that you are trying to run in extended display mode? I thought you wanted more than two displays. If only the TV it should just work if you are not using mirrored displays. Your Displays Arrangement tab should show both your main screen (one with the little whith menu bar) and the TV. Set the proper resolution and refresh rate for the TV using it's Displays preference window. That is all you need to basically do (ignoring overscan/underscan problems).
Note, if you are using Lion then I have heard that when using full screen mode in Lion additional screens show nothing.

Suitable ethernet cable for my new Imac 27-inch iMac 3.4GHz quad-core Intel Core i5 and old imac 1 GHZ PowerPC G4

I am looking for a Suitable ethernet cable for my new Imac 27-inch iMac 3.4GHz quad-core Intel Core i5 (Mavericks 10.9.4) & old imac 1 GHZ PowerPC G4 (10.4.11) for transfering files, documents, photos into my new intel mac from my old power PC imac.
Can anyone please advise me which suitable ethernet cable would be suitable for tasks.
Many thanks
Niall

Note, the iMac G4 1 Ghz only supports 10/100 base-T. Firewire is up to 4 faster with a cable such as this one:
http://store.apple.com/us/product/HA833ZM/A/belkin-firewire-800400-9-pin6-pin-ca ble-2-m66-ft
and adapted to this one:
http://store.apple.com/us/product/MD464ZM/A/apple-thunderbolt-to-firewire-adapte r
http://www.macsales.com/ may offer cheaper cables.
And since you are migrating from a G4, be sure to make your files portable to newer data formats before transferring. Old Appleworks/Clarisworks files are not compatible:

Television and TV Recording with a ATI Radeon X1900 XT 512MB equip Mac Pro

I have been looking into a Mac Pro 2.66-3.0 Dual-core equipped with a ATI Radeon X1900 XT 512MB. One of the things I would like to accomplish is to also use the thing as a television and TV recorder (reliably). I have experience with the a PC equiped with a ATI9700pro all in wonder. I had nothing but problems with the software with hours (weeks) spent trying solve the issues. Turns out this is not an unusual thing with the ATI-Allinwonder. Thought I would check here to see whether anyone has input on how the x1900 works on the mac pro esp as a tv device.

the elgato system is an external tv tuner that connects by USB. It has nothing to do with the graphics card in your mac.
you can connect an antenna, cable, s-video or composite. Some of the models accomodate HDtv now.
the results are clean, and i've had no problems.

Can I replace an ATI RADEON 9800 PRO-(256MB)-MAC EDITION with Mac ATI Radeon 9800 Pro 128mb Video Card For G4/G5

Hi,
I am trying to help a friend whose graphics card has bust.
The old one was an ATI RADEON 9800 PRO-(256MB)-MAC EDITION.
I've been looking on ebay and it seems a lot cheaper to get a Mac ATI Radeon 9800 Pro 128mb Video Card For G4/G5.
Can I just swap them over? The connectors are not identical according to the photographs.
Thanks.

I'd like to thank everyone for all the really useful information in this thread. It helped me solve a similar problem, which I'll describe here briefly in case it helps someone else.
I have a 2004/5 dual 2 Ghz PowerPC G5 and an Apple Cinema HD display linked, as I later found out, with the now defunct ADC connector. The display suddenly started to look like that scene in The Matrix, when code falls like rain down the screen, and I worked out I needed to replace my Radeon 9800 pro video card (I discovered the board was blue when I removed a thick layer of dust).
I took japamac's excellent advice and bought a Geforce 6800 Ultra from the linked eBay seller in Hong Kong, who delivered it extremely quickly, along with the cables to plug it into the DVD drive power source and a CD with installation instructions. It was only then that I realised the card had two DVI connectors and my display needed ADC (I hadn't understood the difference).
eBay came to the rescue again with a seller who had a secondhand DVI to ADC adapter, which Apple produced when it phased out ADC about six years ago but no longer sells. It has its own power supply and looks like a large version of the Mac laptop power cables - and has added signifcantly to the pile of spaghetti under my desk.
Installing the Geforce 6800 Ultra is fiddly, and a bit scary if you're not used to delving into the insides of a Mac, but the instructions were clear and illustrated with useful photos. The video cable has four connectors. Two fit into the end of the card, the other two (linked in a Y shape) form a bridge between the DVD/superdrive and its power cable. You have to remove the DVD drive, unplug it, and then plug one of the two Y video card connectors into the DVD power cable and the other into the DVD drive itself. Then you replace the DVD drive, plug the two remaining cable connectors to the video card and ease it into the old card's AGP slot.
Finally, with the G5 reassembled, plug the adapter's DVI connection into the back of the card, plug the Cinema Display ADC cable into the adapter block, plug the adapter's USB cable into the G5 (this enables the the USB ports on the back of the display to work), and power up.
At the time of writing, the display has been up and running for a couple of hours and all seems fine.
Thanks again everyone for all your help and advice. If it wasn't for communities like this, it would be virtually impossible to solve problems with old but still serviceable Macs.

Can someone tell me how to fix this error in 10.4.11 on a G5 Quad Core 2.5GHz Tower...A valid video device could not be found for playback. [-70017]

That's an error reported from DVD Player I believe...
kDVDErrorMissingGraphicsDevice = -70017, // A valid graphics device is not available.
There's some conjecture it has to do with HDCP, or Video Card problems, but the only 2 cures/fixes I found were Software related, one was cured by updating the OS, another by replacing the Video kexts.
I think this error also shows up if trying to use DVD player in Safe Mode, (too much research isn't good! ).

IMac and video card ATI Radeon HD 4850

Using my iMac 24"/3.06/SD with OSX 10.6 and trying to access Final Cut Express, it tells me I need an AGP video card! Why isn't the ATI Radeon HD 4850 able to display FCE? It operates all my other Apple software. Please, has anyone an idea about this?

Is it better to have two ati radeon HD 5770 or one ATI radeon HD 5870 for video editing?

Is it better to have two ati radeon HD 5770 or one ATI radeon HD 5870 for video editing? I'm basing this question based on the current options when configuring a Mac Pro. Currently there are three options
ATI Radeon HD 5770 1GB
Two ATI Radeon HD 5770 1GB [Add $250.00]
ATI Radeon HD 5870 1GB [Add $200.00]
Between the second and third options I am wondering which will provide a better more productive experience for video editing. Such as using FCP or FCPX. I know how many monitors that are in use will affect the answer to this questions. While I'm more focused on which option will deliver a better video editing experience, lets just say for argument sakes that the Mac Pro is running a 30" cinema display and a small generic monitor. About 18". Its an older VGA monitor for web development.
I hope thats enough info to get an answer on this subject.
Thanks

Ya in my research of this question, I came across this whole issue of Mac not being able to use CrossFire. I didn't thorugly investigate what this CrossFire issue was, but if it makes more sense with the singel 5870 rather than the 2 5770 then thats helpful to know.
If the Mac can't make the most out of two 5770 because it doesn't make use of CrossFire, it seems silly that Apple even bothers to offer it as an option. Plus its cheaper with the singel 5870 versus two 5770. Unless you really needed to run several monitors.
Thanks. This satisfies a long curiousity I have had.

ATI Radeon HD 4870 512MB

Does anyone know if 1 ATI Radeon HD 4870 512MB uses how much power, because in the new Mac Pro (early 2009) it can't use more than 300W of graphics power consumption. So, i am thinking of getting 4 of those ATI Radeon HD 4870 512MB graphics cards (because i'm a real gamer) and stick them all into my new Mac Pro (early 2009)but if it does exceed 300W, then would anyone suggest a powerful gaming graphics card that is both compatible with Mac and Windows as i am planning to get windows vista on boot camp. The NVIDIA GeForce GT 120 512MB is said to be a very crappy graphics card so i'm saying NO WAY!! to the NVIDIA GeForce GT 120 512MB.

Get what you need for OS X, then get a PC card just for Windows. The GT120 might do normal things in OS X and grab whatever you want.... there is 75W and two aux power connectors of 75W each. GTX 275 Nvidia or something perhaps.

Replacement Program - ATI Radeon HD 2600 XT video issue

Mac Pro (Early 2008):
ATI Radeon HD 2600 XT video card with distorted video or no video
Last Modified: March 15, 2011
Article: TS3630
http://support.apple.com/kb/TS3630
Symptoms
Apple has determined that certain ATI Radeon HD 2600 XT cards sold for use in Mac Pro computers between approximately January 2008 and May 2010 may experience distorted video or no video.
Products Affected
Mac Pro (Early 2008)
Resolution
If your Mac Pro experiences distorted video or no video issues and has an ATI Radeon HD 2600 XT card in it, you will need to bring your computer's serial number and the graphics card into an Apple Authorized Service Provider or an Apple Retail Store location for verification and to exchange the affected graphics card for a replacement.

The replacement process as stated here
http://support.apple.com/kb/TS3630
is not correct.
Here is my first hand experience:
Have had the intermittent problems as described almost since the computer was new. After many calls to applecare and ROM upgrades, software upgrades and reinstalls, new boot drive - problem persisted until last week -now monitor stays on black screen on startup.
Called local Apple store as described in support page - they know nothing about it and you cannot talk to a tech on the phone - have to make appt. Asked the receptionist to please describe problem to tech and see if they might be able to help before I take the time to make appt. I was told that they don't handle that here - go to an outside service center. Of course its Friday and the outside service is closed until Monday. Call another apple store and make an appointment - they seam more willing to help.
Follow the instructions and remove board and take it with Mac serial number to store.
I am told that they will not release the replacement board unless they install it themselves in my computer. I politely point out that the service doc states otherwise - no dice. Tech orders the board - won't know until Monday what delivery schedule is - he guesses 2-3 days and they can install when it comes in.
Lesson learned.
You can't trust what apple says in a tech document - maybe you can't believe anything they say. Frustrating part is that you can't talk to anyone to get a straight answer until you nail someone down in person - and how do I know that the tech told me the right thing. After all, doesn't corporate dictate policy? I got the policy from the corp site. So which is right?
Do you think they would reimburse me if I went out and purchased a new board and did the replacement myself?
"If you believe you have paid for repair or replacement because of this issue, contact Apple regarding a refund."
I highly doubt it based on what the tech said - but who should I believe?
