As posted from my favorite site, Shacknews.
I know many of you are hardcore ATI fans or vice versu, i didn't start this thread for a flame war, i know some of you aren't keen on dropping big bucks on the newest and greatest cards, so I figured i'd post a semi inexpensive card that may be another option for you. 
I'd say my one miff about the cards at first is the whole PCI-Xpress only thing 
GeForce 6600 AnnouncedNVidia today announced the GeForce 6600 series, which will include a regular version of that chipset along with a GT version. Both these cards are considerably more affordable than the 6800 cards, with the regular 6600 card setting you back $149 while the GT version will be $199. Though the press release mentions they'll have awesome performance in DOOM 3, that of course remains to be seen. There's a benchmark-less preview on Tech Report.
