I had a 9800 Pro (well, I still "have" it, but I'm not using it anymore, got a new system, it's resting in peace in its original box) before.
I had it since late 2003 until three days ago.
Went through many Catalyst versions (WHQL versions that is).
I tell you mate, I never, ever had a single issue due to drivers. Other than the casual "performance changes" it provided, or not (it was usually just in-game bug fixes, and rarely actual optimizations for specific games).
The best driver (if I recall correctly) I've personally ever tried, were Catalyst 4.11 / 4.12, followed by 5.2 and 5.11.
Perhaps I was lucky, but none of my games crashed due to drivers ... from what I know anyway.
Oh, and, so far, and since I know and buy ATi products (Although I do own nVidia products as well right now), I haven't even tried that famous Catalyst Control Center.
All I did was downloading the Display Driver only, and make changes via Rage3D Tweak, or ATi Tray Tools. It worked like a charm.
Eventually (not so long ago), Rage3D decided to move to CCC with their Tweaking application. It now only works with CCC. Sad, just because ATi themselves don't "support" the good ol' Control Panels anymore.
It just looks more fancy, but I hate the interface according to pictures I've seen.
Right now it's: ATi Tray Tools 4 teh w33n.
And if I might add: Vive Catalysts.
