Is the i7 GPU [enough] for two displays?

Hi,

Im building a computer for work and Im thinking of using the built in GPU in i7, will this handle 2 Displays in 1920x1200 without problems?

I could add a fanless PCI-Express GPU but this will make the temp to raise a bit i guess?

BestRegards

Yes, it will work. This has very little to do with GPU power btw. More a question of features, as long as you don't plan to do any heavy 3D work or play games.

If you're just using the computer for productivity, i.e. not anything GPU demanding, then the i7 will easily handle the two desktops.

Thanks, this sounds great!

I thought is to extend my desktop on two displays that each run 1920x1200.

No gaming or heavy 3D will be done on this computer, just winform development. Ofcoudes some internet browsing also with flash and so on.

Yep - the iGPU will work fine.

What about two 1920 x 1200 displays running CS6 and/or playing Blu-ray videos?

Two displays at 1920x1200 is fine, bluray is fine and CS6 will work but I think it could perform better with a better GPU.

While Adobe has added Open CL features to CS6, I haven't seen how much gpu is really needed to make full use of it. AMD claims ~5-7x speed improvement on Blur and Liquefy filters using a Llano laptop APU...so HD4000 might be in the same ballpark.

I think how much of a boost you'd get with photoshop CS 6 by going to a GPU would depend on what filters you commonly use.

Is it just Open CL, or does Adobe also support CUDA? IIRC, the latest batch of nvidia cards aren't so great WRT open CL performance.

lhopitalified: CUDA is an NVidia only deal. I hate to suggest getting a discrete GPU without seeing any benchmarks.

Whispercat: Try it with the iGPU and compare to your current platform...it might be in the land of "good enough". If it isn't, you can always add a discrete card.

Thanks, will do. That's good news about the Intel HD 4000 being able to drive high res displays and Blu-ray.

If it turns out not to be quite good enough for CS6, can you recommend a low power discrete card? (I've been out of the video card loop for a couple of years).

Hopefully, there will be some CS6 gpu benchmarks/reviews out in the next month or so and we can figure out the optimum card. You shouldn't need much :D

For CS6 or CS5.5 you definitely want a nVidia GPU as the performance difference is dramatic.
CS5.5 is CUDA only and you want at least a GTS 450.
I understand that CS6 benefits from both CUDA and OpenCL so again nVidia is the only way to go.
For CS5.5 it was straightforward but the situation with CS6 is more complicated (nVidia 5 v 6 series) so checkout the Adobe forums:

Huh? Open CL is supported by Intel, AMD and Nvidia. As for Cuda, I guess it depends on whether the user is talking about Premiere (useful) or Photoshop (not useful).

From http://forums.adobe.com/thread/979969:
MGE is new to Photoshop CS6, and uses both the OpenGL and OpenCL frameworks. It does not use the proprietary CUDA framework from nVidia.

They only mentioned CS6 so who knows! For full support under CS6 go for nVidia otherwise be prepared to spend some time monitoring the Adobe forums and other sources for info.
