Graphic Cards for Resolve - 2 needed?

Hello,

I just ordered a GTX 680 with 4 GB Ram for my i7 930 1366 Plattform PC.
That goes together with my GTX 460 1GB OC from Gigabyte.

Does that combination work? Or is it better to have only the GTX 680 to avoid problems.
How to select which Graphic Card is for the Interface?

I will also work in CS6 Cloud Aftereffects and Premiere.

Thanks.

Isn't placing 2 different graphics cards going to disable one or the other by default? I've personally never seen a computer with 2 non-SLI/Crossfire mode graphics cards working individually on the same motherboard of a PC.

Two different cards should work fine. If application is capable of using cards independently (as Resolve should?) then no SLI config is necessary.

It should be fine with the two cards, though you will want to make sure the least powerful of the cards is setup for use as the GUI board so that the stronger card will be available to do the CUDA processing.

Nope. It's the recommended setup for a DaVinci Resolve system. One GPU is dedicated to image processing and shouldn't have any monitors attached to it. The second GPU is used for the graphical user interface.

Resolve's Configuration Guide (downloads with every install of Resolve and Resolve Lite) goes into mind-numbing detail on this and should be required reading for anyone putting together a Resolve system.

Since V9, a single GPU should work fairly well for you at well. We get about 13 nodes of image blur with a GTX 570 card, no GUI card. Get lots of GPU RAM though - see our config guide for details.

You can turn on the "Use optimized display mode during playback" in "Video Monitoring" section of Project Settings, Master Project Settings to get more performance if you need.

Of course, a dedicated GUI card always helps, and you definitely need it when you are going to a PCI-expansion box with multiple GPUs.

Hope this helps!

Thank you for your insights. Those were very helpful.

Thanks to your suggestions I read the Aug 2012 configuration suggestions from blackmagic support section and I follow it (Motherboard,CPU,GPU,RAM) with my new system.

Only my gfx card for GUI (GTX 460 1GB) might be outdated or too noisy.
I will test and report.

Best Regards

Well how did you get on? Im doing something similar here. Did you used your main graphics card for procesing and the second one for display? can you manage to get a full preview video on a second monitor? or you need the intensity pro to get the preview on second monitor?
