IMac Video Card in 20" and 24"

Hello,
I want to thank everyone in advance for posting
here.
I am deciding between the 24" and 20" iMac but will
be doing the video card upgrade regardless of which
system I buy.
Can anyone tell me the difference between the upgrade
options (nvidia geforce 1600 gt in the 24" and the
ATI Radeon X1600?
Actually, if you look at the specs at the online Apple store, you will see that the 20" offers the x1600 with a choice of 128 or 256MB of video ram. The 24" offers the Nividea 7300 w/128MB or the 7600 with 256. IF you are going to be doing video editing and photography, I would get the upgraded model no matter what system you get. Though it may be theoretically possible, it will be very impractible to upgrade the card later. You will need the ram,especially if you want to play any games,or get into Aperature for photo management and processing as well as CS2 also, I think it would also impact video editing as well.
BTW, the 24" screen is great.

IMac video card is busted again. Options?

I have a 27" iMac purchased in 2011. Since this January I've had to take it to Apple Retail Store for video card replacement twice, and now it's busted again. I don't want them to put in another refurbished card and likely break down on me in a short time. So far it's costed me 6 days without my computer which I use for work.
My question is what options do I have to prevent having this problem again and again?
I do get free repairs via Apple Care but I shouldn't have to deal with so much down time. I feel that I should be compensated somehow, or at least be guaranteed a new, not refurbished, video card.

first, call AppleCare and complain in a polite manner so they can document the situation, also have them make an appointment for you in the genius bar and have them give you the case #. Then go to the appointment and ask for a new one after you plead your case about how much you have been inconvenienced. I think you have a pretty strong case.

So which 27" iMac Video card to go with???

Hey gang-
Lucky me- my wife said that I've been good enough to ask for a new iMac this Christmas! I'll be replacing my trusty old Mid-2007 24" with one of the new Late-2013 27" models. To my surprise, it seems my go-to source for reviews- MacWorld magazine- has yet to publish any print review of the Late-2013 models- so I'm guessing they aren't going to.
I know I'll be going with a Fusion Drive upgrade, but where I'm stuck is on the Video card. Thoughts on the NVIDIA GeForce GT 755M/1GB, or the NVIDIA GeForce GTX 775M/2GB, or the mac-daddy NVIDIA GeForce GTX 780M/4GB?
I've seen a few threads with new owners of Late-2013 iMacs already enquiring about upgrading their video cards, so don't want to underbuy.
Any thoughts or maybe anyone found a good review since MacWorld hasn't?
Thanks!
Dave

What are you going to use your new iMac for?
That will determine what CPU and video card you need.

IMac Video Card Replacement

Is there anyway to get the video card replaced in my iMac? Apple Care has expired and they replaced it just last year before it was over but it appears to have gone out again. I have a 24" Intel iMac which I purchased in Feb of 2010. I read online that it is not possible to replace myself because its sealed in but I recall when Apple replaced it last year the Genius telling me they just pop it out and replace but maybe I misunderstood.
I'm not sure why it has gone out again we barely use it as I mostly use my MacBook. However, the MacBook also seems to be having issues with its video card.

You will need to take it in for repair. You don't even know that the GPU has gone bad. It could be something else. If you attempt to repair it yourself, then Apple will no longer provide any future support whatsoever. Let them do the repair for you.

Mid 2007 iMac video card does not meet minimum requirements for latest iMovie update

Tried updating to the latest version of iMovie and I get the following message. "Your computer's video card does not meet the minimum system requirements." I haven't had any luck finding what those requirements are. What are the minimum requirements?
Thanks.

I'm having the same issue here too. I'm using a mid 2007 iMac 2.4 GHz Intel Core 2 Duo with 4GB of SDRAM and ATI Radeon HD 2600 Pro 256 MB.
What bugs me is that the update shows up but you are not allowed to install it. Either one of two things needs to happen.
#1 apple allows users to hide the update but still let you know that there is a hardware incompatibality
#2 don't let the update show up at all

Which video card for Aperture and dual monitors?

I have a G5 dual 2.0 with a GeForce FX 5200 video card that is driving one 23" Cinema display. I need to upgrade my card per the specs to run Aperture. I have also been thinking of getting a second 23" display. Can someone recommend the best video card for me. I know very little about video cards and have been reading a lot this morning. Thanks,
Dave

Hi Dave;
No. PCIx and PCIe or PCI Express are not the same thing.
PCIx is an extended or slight sped up version of PCI. While PCIe is a switched bus structure instead.
Hence they are not the same. That is what all of the big news is about Apple has made the leap over to PCI Express.

Video Card for Premiere and Photoshop?

Hi.   I thought I was reasonably well set up when I got an nVidia GeForce GTX 470 for video editing.   Unfortunately life throws us curve balls...
I'm upgrading one of my current monitors to a much better quality IPS-panel monitor.   At the top of my list is the NEC PA271W-BK-SV. To use it at it fullest, apparently you need to use its DisplayPort.   Which of course the GTX 470 does not have.   So...
I'm looking for a good quality video card that has both CUDA support and a DisplayPort that supports a full 10-bit per color display pipeline. Right now, the only one that I can find under $1,000 is the NVIDIA Quadro FX 3800. Anyone have experience with this one?   Better options at a reasonalble price point?
Thanks and regards,
Dan.

Harm,
That looks like an absolute winner!   Many thanks!!!
Dan.

Video card for HD and green screen

I use a windows XP64 based machine with a quad core I7 920 processor and 12 gigs of RAM with nVidia 260 card. I use CS3. Right now I am having severe crash issues in Premeire CS3.
I do HD 1080i video editing with up to 4 layers of green screen. I currently use Adobe AE Keylight2 for my greenscreen work. I bring the files into Premeire with "Dynamic Link". I crash, and crash, and crash. What is my best option to prevent crashing. A Quadro video card? which one? . Or, Matrox Max. My budget is somewhat limited. I can't get both. I want to upgrade to CS5 but need to fix this problem, now.
Sincere thanx to anyone who can help

I appreciate the quick answer and am considering moving to Windows
7 (64). What is the sad story about Matrox? What is the best way to speed
up my rendering or processing without having to purchase another cpu? Thanx once again for your quick response. I render primarily to h.264

Series of problems: Dedicated Video Cards turning ON AND OFF

Hi guys. It's been a long time. I'm back with yet some more problems.
After weeks of happiness with my wonderful computer (Toshiba Qosmio X305-Q706) I started finding some more issues with it. My laptop has three video cards as can be seen in this post: [Click ME].
One set is the integrated graphics card, an nVidia 9400M, and the other set consists of two dedicated nVidia 9800M GTX working in SLI.
What is the problem? At any given point the dedicated cards activate and deactivate continuously four or five times. This cycle can repeat itself two or up to four times a day.
Is that it? No. The set of cards are acticated&deactivated because the Windows Power Plans are being changed by an unkown agent. Whenever this thing starts it's because something is cycling through the power plans in an order I haven't bother to check but I know it goes through all three of them: Balanced, Power Saver and High Performance. I figured this out because while it was happening I had the Power Plan popup open and saw the radio buttons switching by themselves.
Is that it? No. When I wrote unkown agent, it wasn't so unkown. At one point I tried to run the Task Manager and keep a close eye on the list of processes running. Oh incredible is me. I found that for each time the power plan was changed, a process that went by "dllhost.exe" was causing the pain. See here:
At one point there were more than four of dllhosts. I looked it up and found that dllhost is a neutral Legit Microsoft file but can be manipulated to do "bad things". A few days later I still had the problem and checked the running processes with another program that replaces the task manager called "Free Extended Task Manager" by Extensoft. What surprised me was that when the thing was going on where there were supposed to be dllhosts therewere rundll32s instead. Should there still be rundll32 in Vista 64bit?
Sometimes, after the cycle is over, this error window will pop up:
I have no idea what it means. Sometimes it accompanies every turn the dedicated graphics set is trying to turn off. I suspect it pops up when the cards weren't able to shut down.
When I switch from the dedicated set back to the integrated card the fans won't shut down. Even after 12 hours they're still running at full speed and the air they're blowing out is practically cold.
That's all I gathered. I hope somebody can help out.

No, I am not saying it is bloatware. Actually bloatware is anything that you don't need...
In this case I meant try that as a troubleshooting method. If it is the case, then we can try reinstalling it.
You don't have to use the Tsohiba power management, or many other Toshiba software services. It just comes down to if you need what those things do. When they are working fine they don't seem to be CPU hogs so i usually leave them alone. I did remove Toshiba power management on one laptop because it caused a problem and I was too lazy to do troubleshooting. Also I was using the laptop as a desktop, always powered, so power management was not an issue.

GX60 shows two video cards? 7970M and 8650G.

I updated to the latest ati drivers, and now my laptop, GX60, thinks I have two video cards installed, a HD 7970M (true) and a HD 8650G (not true).
If I uninstall the 8650 under device manager, I am then unable to run the catalyst control manager, as it doesn't think I have a graphics card. This is even though the 7970M still shows up under devices.
Also, now when I run a youtube video, it shows as a green screen, with audio. I read that I am supposed to disable hardware acceleration under the flash menu, but that tab doesn't show up, which I believe is related to having messed up drivers.
What do I do?

Em, no both is true. Your notebook HAS two gpus. The HD8650G is the integrated gpu of your AMD A10 APU. The 7970M is only active when 3D load is applied while everything else is covered by the integrated HD 8650G gpu.

2007 Aluminum Imac Video Card upgrade

I asked this before but I think i didnt ask the question correct. I have a 2007 Aluminuim imac.
I was curious if you could upgrade to the 8800 video card in the latest imac.
Sorry I was confused.
Tom

Actually the answer is YES, GPU is not integrated on the motherboard, it is a removable standard MXM format GPU.
Please check out this blog (scroll all the way to the bottom)

A whole other issue is where to purchase an Apple compatible MXM GPU.

Detect video card in 32 and 64 bit.

How can I get both the 32 and 64 bit versions of CS6 to detect my graphic processor (AMD Radeon HD7700) for GPU usage in Win 7 ? Cuiurently, it is only seen in 64 bit.

Thanks again Chris.
I again completely uninstalled the AMD Catalyst and drivers and reinstalled the latest one from their site. I am still unable to select Again, the card is not detected in the 32 bit version of CS6 and is readily available in 64 bit. Also very interesting is what the System info shows. i.e. Windows XP and yet I installed the lastest version of CS after I had updated to Win 7 on a new computer.
Here's what the system info shows in CS 6 32 bitr ..

In my powerful mind, it appears that CS will only see the card in the 64 bit version. Not that it's a big problem with easy work-arounds but it puzzles me and I was hoping that someone else has had a similar experince and was willing to chime in.
Appreciate your time.

Best Video Card for Editing and Rendering?

I bet this topic has been discussed at length, but doing a search for "best video card" did not give me the results I need. I am working with the latest version of Magic Bullet Movie Looks and started to notice artifacts in rendered video; flashes, black/white lines and complete boxes in the final frame. I contacted Red Giant, and they informed me my Quadro FX 1500 is not a "supported" card and is most likely the cause of these artifacts. Strange, as Movie Looks had Quadro FX 1300 and up as listed on their web site as compatible - but I digress. My question is, what video card do YOU like for PPRO CS3 AND AE? Movie Looks, like many other programs, rely on the video GPU to render their output - what has been fastest for you, and NOT caused issues with the rest of the system? I use video overlay (as part of Nvidia's Dual View) to edit the Program ouput on a separate monitor and also need this functionality as well - can't live without it! Thanks for your answers.
System Specs:
Dual core Dual processor Woodcrest
6GB RAM
2 TB RAID HD
Current Card: PNY NVidia Quadro FX 1500

Well, if you go to Adobe's hardware compatibility page is does list the 7800 as being fully supported:
http://www.adobe.com/products/premiere/search_result.html?manuSearchVar=1&modelSearchVar=0 &supportSearchVar=0&brand=&dataFormat=&version=CS3&device=graphic&format=
but the 8800 series cards are also listed, which will support CUDA once it becomes widely used. CUDA is rumored to be utilized with CS4 which will speed up render and preview times drastically by utilizing the GPU as well as the CPU rather than mostly the CPU only.
http://insidehpc.com/2006/11/10/what-is-cuda/
This could still be a year or two away, so if you think you may upgrade your video card again before that time, you may want to stick with the 7800 for now.

Question about iMac Video Cards and Video Ram

I'm trying to decide between two 2012 iMacs. I'm buying it to run Adobe Premiere Pro, and After Effects, to edit and render 1080-720p video footage. The cheaper Mac has NVIDIA GeForce GTX 675MX graphics processor with 1GB of GDDR5 memory. The higher end one has, NVIDIA GeForce GTX 680MX graphics processor with 2GB of GDDR5 memory. Most importantly, is the extra GB of Vram worth it? Secondarily, is the GTX 680MX(vs. 675MX) worth it? I'm trying to keep it cheap, so unless there's a notable difference, I need to go with the first one. Thanks for the help!

mostly video memory is used to hold textures for fast blittering when one run fullscreen 3d games 2d image program and video edit programs does not really take advantage of more video memory then they need to hold the back buffer of the screen which is pretty much just horizontal amount of columns multiplied by vertical lines multiplied by 4 as in the 4 bytes used by the colours

FCP on iMac - video card RAM

What are the benefits from boosting video memory on the 20-in iMac from 128 MB to 256 MB? I'm interested in the effect on performance while using video editing software such as Final Cut Pro. Thanks!

Hi:
I thought you was trying to upgrade an iMac you had, but you are getting a new one !
Motion will be the FCS program to take great advantage from your graphic card processor. Motion is GPU based.
The other componentes of FCS are CPU based. From FCP v5.1 you can use some of the Motion effects what means that your GPU power will help there.
I'm pretty sure you have visited this page:
http://www.apple.com/imac/graphics.html
Here you can find the Motion graphics requirements:
http://www.apple.com/finalcutstudio/motion/specs.html
Your best option is the 24" with the 7600 GT.
Think you'll need a second drive (external) to store your captured video.
WHY DON'T YOU . . . ?
Probably you'll get a better and more flexible FCS station getting an used PowerMac that you can "dress" with better options to use FCS: second internal fast drive, graphic cards, etc.
