Atrail : The 8500 is a great card if you have the time and patience to get it working efficiently, I've tried three different driver sets since last weekend when I brought it - originally I had serious problems with font and texture corruption whilst looking at the Windows desktop and playing certain games (AvP2, Renegade and CS all spring to mind).
Tates : I tried the Redsoft drivers you suggested a couple of days ago and they are certainly better than the standard drivers supplied by Rage3D, most of my 8500 based problems have now vanished. Cheers for the link!
Now the only problem I have is when I take a screenshot using print screen the resolution on the fonts come out at a very low resolution. Its weird because the desktop looks fine to look at, I print screen and copy it into a paint program (tried PSP7, MS Paint and Fireworks) the fonts are really blockly - Solutions??
