Everyone says this, but I've never had any problems with my Radeon card. I certainly DID have problems with the GF2 MX I had before it! Either way, I consider the fact that the Radeon is MUCH faster to be worth a few possible driver bugs. Also, ATI is now regularly releasing driver updates as well.
Either way, I'd either go with the Radeon LE or maybe get the Kyro II (3D Prophet 4500).
Radeon LE!! Im kind of excited about the Radeon 2 coming out later on this year. Probably in a years time ill actually be able to afford one.
I also hear a Radeon 3 or a two chip deal will be out in jan or so. Cool eh?
