I bought a new GeForce 7900 GT "OC Series" from BFG Tech, with 256 MB of memory and it has a strange problem... When using the card in the resolution of 1280x1024 and AntiAliasing 4x or higher, the 3D graphics become corrupted, like this:
If I put the AA setting to 2x there´s no problem.
I have tried several drivers, even re-installing Windows more than one time, also, with no success.
Might the card be defective? Some sort of incompatibility with my hardware?
It´s A64 X2 4600+ on an ASUS A8N-SLI32 Deluxe, with 2 GB Corsair... And the power supply is a SevenTeam 500 Watts.
Thank you in advance for any clue!
