A good website for anything ATI is
www.rage3d.com
Check out the forums there for a ton of info on Radeon stuff. I'm a radeon user myself, and this site is a godsend. Yes, it can be biased at times, but what do u get from an ATI fansite? They have some useful utilities that can help clean up stuff. You might want to pick up the latest Catalyst drivers for your vid card as well. Word of warning though, don't download "Built By ATI", you'll want "Powered By ATI" There should be something for Saphire boards as they are one of the bigger OEM companies supporting ATI. I've found that ATI drivers on OEM boards either don't work altogether, or cause weird glitches and instability in games. Hope that helps!
