If it is not too late, do NOT get an ATI card. I owned two different ATI cards and they have to be the worst cards I have ever worked with. The software is always full of glitches and gotchas. Every game I ever owned had problems with ATI cards. I replaced both of them with GeForce cards and those same games all worked perfectly! One is a GeForce 2 Ultra (very good at the time and still works great) and the other is a cheap GeForce2 MX420 that I picked up from WalMart for $50 about 3 months ago.

All the game websites say the ATI Radeon is a good card, and it might be, but as long as it says ATI on it, you will never EVER find on in my PC! If for some reason you do get one, find a version of the software drivers that works and do not ever install an update to it.
