I find ATI products to be fairly solid hardware-wise, but they do need to better their driver QA.. My wife is running a Radeon 8500, and my uncle is running a Radeon 7000 - both on my recomendations (My wife got the 8500 when it was the big ATI card, and my Uncle got the 7000 because it is good and cheap - as in $50 at CompUSA for 32M AGP). The problem is that their newest Catalyst 3.0 drivers, while faster then the 2.x series, don't work well with Medieval: Total War (text on menus flickers) and MechWarrior 4: Mercenaries (The background video on the main menu COVERS the menu so you can't see what you are clicking on). I have informed ATI of the problem through their customer service link, but they just brushed me off and told me it was probably ajust my software. This on a fresh install of Windows! I had to downgrade my Uncle to Catalyst 2.5 so he could play these two games. This is of course a far cry better than the laptop graphics abortion known as the Rage Mobility M1 I had in my last laptop.
On the other side of the coin, I also remember back in the day (lol) when 3DFx was king of the hill and the TNT & TNT2 cards were new nVidia device drivers were equally horrible. I remember one customer to the computer store I worked in back then needing something like 5 different versions of the video drivers to play all his games. He'd just load in whichever version worked best with whatever game he wanted to play! Also, there was the time a friend of mine bought a TNT (Diamond Viper V550) for his 350MHz K6-2 computer using the VIA MVP3 chipset - that was pretty hellish. Took 2 months to find a VIA AGP driver and nVidia driver combo that would leave his system stable and usable. I swore I'd NEVER buy an nVidia card (now I own a GeForce 3 - nothing less could wean me from my Matrox G400 Max) Oh, the memories!

PS - If the Matrox Parhelia had lived up to my expectations, I'd own that. Nothing, and I mean NOTHING can touch Matrox on picture quality, sharpness and color vibrance. I hooked my G400 Max up to a crap monitor once, and it made it look GOOD! This card lives on in my Dual P2-350 workstation.
