I too still find to many damn issues with ATI Drivers. The last 2 releases have broken Quake 3 for me. Both still play, but the Gamma is now totally screwed up (almost 0 light) Going back to earlier drivers fixes this, course then other things are broke because of using a few month old drivers.
Another thing that sucks is MultiMon issues. Half the time on reboots, it forgets that I have 2 monitors, shuts my main one off, leaves my secondary on. Unfortunately its a pain in the arse to login and change the display settings when they appear on the Primary Monitor (which, for those of you not following along to close, is now turned off!!!)
I used to use a TI 4800, and I would never have to think about these issues. I upgraded my drivers because every 4 months I could get a 30% speed boost. Now I have to update just to make sure my games work. That sucks.
Another thing I noticed, whether its a hardware issue or a driver issue - My box crashes in games now. Windows is still running, as I can get access to shares, services, etc from a remote box, but my damn video card is froze. Half the time it decides to come back to life, the other half I have to reboot. (yes, I have VPU recover turned on. Its very telling about the hardware that it even NEEDED to be an option) I currently have a Radeon 9800XT in my box. My old TI4800 is in my other gaming box (both systems besides the Vid card are almost identical, same mobo, CPU, ram, and HD - different CD/DVD stuff and case) Needless to say my other box doesnt crash.
So I am now left with a choice. Either lower my resoultion, and turn down some AA and filtering - but play any game, when I want, and not have to worry about crashing. Or play games in full glory in short stints, and fight for a few mintues to get my primary monitor to come back on after the inevitable crash.
Can you tell I am hoping that nVidia gets their act together so I dont have to make a comprimise?
