ATI still has crappy drivers, period.
Their business model seems to be, "Hurry up and get a piece of hardware on the market, we'll worry about drivers later!"
Yeah, MUCH later, sometimes 6-12 months before there is a decent set of drivers.
Forget it. I joined the ATI camp when the R8500 came out. One of the worst hardware decisions I ever made. I spent so much time trying to get that card working, it's pathetic. THE WORST hardware decision I ever made was getting a Radeon 7500 AIW a couple weeks ago. How long has this card been on the market? The drivers are still screwed up. Messed up my Win2K so bad, I had to format and reinstall.
One thing I'll give Nvidia is that they make good drivers, consistently. I've never had problems with Nvidia's drivers, but I've had nothing but problems with ATI. I've had at least half a dozen ATI cards that have had drivers issues consistently, for YEARS!
