Mikhailtech has published a Basic System Buyer's Guide

Thanks to dropping prices, this month we were able to give our video card a slight boost. We're still recommending a Sapphire Radeon 9600 PRO, however this time around we were able to get the 256MB (vs. 128MB) version. The extra memory helps in certain cache-intensive, high content games (such as World of Warcraft). Having full DX9 and OpenGL 1.5 support as well as 400MHz core and 446MHz memory clocks allows this card to play all the latest titles at least on medium settings. We're only a few dollars shy of a 9800SE (though it's a toss up between getting the 128-bit or 256-bit version) or a vanilla GeForce 6600 (non-GT). Hopefully next month we'll be able to make the switch.
