Vertex Shaders Error Message

[Frustratedgamer]

The 2600Pro AGP isn't supported by ATI. I have to alter the driver installation files to get it installed. That might be an issue.

Basically I want to play PBP more than I want to play Crysis or Mass Effect or GTA4 or Gears of War or maybe even Portal, so I'm probably going to buy a new video card to do so. The thing is, it seems like all I can find are clues as to the hardware requirements.

Is there a more complete compatability list? For instance, a list of cards that utilise Geforce3 chipsets : '9 series', '8 series', '200 series'?

The suggested Radeon solution is much clearer, but I might just end up with the same driver issues.

Is there more specific information? Fuller lists of compatible video cards? Can you suggest a card or cards which should definitely run PBP?
