Hi folks

I was wondering if I can run 2x SLI ASUS GTX 760 cards and still benefitting from SLI performance in 3 monitors Nvidia surround mode at 5760x1080. I'm asking since the NVidia Hardware Requirement configurator page in the web does not show results if I select the surround configurator SLI mode on the 760 Card I just can use single gpu mode to get results.

Thanks for your help

Cheers
Marc

I can tell you one thing for sure, I purchased 2 ASUS MARS 760 gpu's a month ago, and set it up in quad sli, (quad sli because each gpu is a dual gpu) and ran 1 monitor fine for weeks--then I decided I would purchase 3 BENQ 24" 1080p monitors, and when I hooked everything up, couldnt play even 1 game... PC would crash every time---I called ASUS tech help around 10 times to no avail--they are useless there---Finally i removed one of the gpu's and walaa! It works wonderful!!! :) Apparently they do not have driver support for running 2 MARS GTX 760's quadfire in Nvidia surround. They might want to mention that on these websites that sell the MARS 760 because if you have or plan on running any 3 monitor set up with 2 MARS 760's, you cant--there isnt enough VRAM on the slave GPU in a Quad SLI Setup, and the way ASUS has nvidia surround set up now, you have to hook up 2 of the 3 monitors to the bottom (slave) gpu, and it does not have the gas to push 2 1080p monitors---If and when ASUS comes out with a driver that allows you to hook up 2 of the monitors to the main card and one to the slave, it should work fine, but until then, you will end up with a $650 brick. Happy Gaming!!!! ~~~Suferbus

Vram, when setting up multi monitors, Vram is very important. I don't think the GTX 760 is suitable for such a resolution. I would suggest the R9 290/x cards as they sport a 512bit memory bus and 4GB of Vram. Remember Vram doesn't stack, so SLI will not stack the Ram. Go with preferably an R9 290x or GTX 780.
You can then crossfire/SLI those cards in the future or purchase two outright.
With the GTX 760 just stay with single monitor, 1080p is what it was designed for.

I was able to run my 3 BENQ 1080P monitors in NVidia Surround with 1 MARS, no issues. FPS on CRysis 3, ultra settings, A/A off was 70-100 FPS, never dipping below 60---METRO Last Light was similar results. My main issue was trying to play these titles when I installed my second MARS 760, which is virtual Quad SLI. It would play these titles on a single monitor with no issues, but when I tried hooking up 3 monitors, no go. So it cant be a VRAM issues if 1 card works fine on 3 monitors but 2 cards don't... It has to be a driver issue, which i do suspect because it is hard to find support for quad sli in any configuration.
