Hi, I just picked up a second nvidia 560GTX card for a SLI setup and I seem to be having some problems. When running battlefield 3 on ultra I get 60fps but every now and them my FPS with spike down to a flat 30fps. It seems as if one of my GPU's is no longer rendering and thats why its cut in half.

My system setup is:
AMD 1090T (O/C'd to 3.8ghz)
Corsair h50 liquid cooler
2x4gb DDR3 1600mhz
2xnvidia 560GTX GPU
1TB HDD
60GB OCZ SSD
MSI 990FXA-GD80

I've tried with the latest beta drivers as well as the latest release drivers.

I've heard a lot of others having issues with the 560TI in SLI during Bf3 so might be a drivers issue. You definitely aren't alone.

The problem is actually video memory. The basic 560's have only 1024mb of memory and if you set bf3 on ultra with the msaa on 2x or 4x the memory requirements exceed the memory on the card so it begins using system memory.
