I was having some video problems while playing on the 64 man servers like ours here at TPG. I called EVGA this morning and the tech had me check my voltage in the BIOS and then had me get a FIRMWARE update for my video card here:

EVGA Forums

Just click your video card series and download the zipfile update and follow the intructions. It helped my video card alot.

EVGA is aware of the problem and is working on a solution with DICE and EA.
