I was sort of thinking of posting a similar thread but asking for advice. I have practically the same machine but am having major graphics issues.

AMD 64 3800+ x2
1Gb Memory (soon to be upgraded to 3Gb)
7900GS
19" CRT @ 1600x1200 ~ 75Hz

I'm only trying to run two clients, each is on a separate HDD but are otherwise identical. I use Keyclone to broadcast keys but I don't use a maximiser.

Even with all graphic settings set to best option for speed, my main screen flicks between 30FPS and 7-8 FPS constantly. The alt screen is set to stay at 10fps when not active and that works.

Thing is the board I have now is supposedly better than my old broken board yet I never had these issues on the old board. Current board is a WinFast nForce570 SLI with all the bells and whistls my old board was a non-SLI cheapo (well cheaper) cutdown everything...

Any suggestions?
