evga gtx 760 SC & Normal SLI poor performance

Just bought another EVGA GTX 760 2 GB and I SLIed it into my computer. The rest of my specs are i7 920 2.67 GHz (Overclocked to 3.82 GHz) with an ASUS P6T D0 motherboard. 8 GB Ram. BFG Tech 1250w psu. Drivers up to date, version 331.40. I was wondering why I'm getting even a worse performance in Arma 2 and Arma 3. While I know these are 2 CPU intesives games I could easily run them on a single GTX 760 before I purchased another today to SLI, now I run on 20-30 FPs for some odd reason. I also noticed my fps going quite low compared to what I expected on other games, sorry I can't be more specific but I was wondering if I was doing something wrong. I reinstalled my drivers and rebooted my computer, I enabled SLI via NVIDIA Control Panel. Right now I really am thinking of getting a refund on my card since it is a total waste of money with little to no performance increase for the most part. I was thinking about the card differences, everything about both my cards are the same except 1 is Superclocked and the other is not. However I doubt this makes a difference performance wise. Another note is this is my 3dmark with just 1 card and this is with SLI The scores seem to make sense but when I actually play games the FPS can go from 60 to 120 and event hough on Crysis 2 and Battlefield 3 from what I've seen and those are good FPS altogether, but its too much of a big FPS drop.

Apparently Arma 2 and Arma 3 have a horrible SLI support.

Welcome to the SLI/Crossfire world - sometimes it works, sometimes it does not and sometimes it even mages to screw things up.

For example my Radeon HD 6990 works better in a single GPU mode in Saints Row 3 than in a Crossfire one.

My next GPU setup will be SLI/Crossfire free.

You can run the game with some command line parameters to squeeze out more performance

You can also add:
-maxvram=2046

Arma is bad with SLI/Crossfire, so can't help you with your SLI problem. But hope the above is helpful :)

I got rid of SLI, was a waste of money. I'll stick to a single card for now until I upgrade my CPU & Motherboard to get guaranteed max performance for my buck. This thread can be closed now, thanks.

you know there are plenty of people using sli and it works great, so its not a waste of money, its just you couldnt be bothered troubleshooting, go buy a ps4 or xbone if you want to game without having to touch settings.
