Does anyone else have any small glitches with this card ?

I have the latest drivers but I wonder if there are any tweaks that you guys know about. I am a complete newbie to Maya and although its not crashing my (Athlon 1800Xp WinXP 512mb ram) machine, its a real pain at times. I sometimes have to move the screen about to stop large objects going completely white as I pan, dolly etc

I have also heard that image planes can be tricky using this card (havent tried yet)
