I was wondering, if it would be ok to save some money and buy a PCI XFX nVidia GeForce 6800 ULTRA, what are the major differences for the AGP ones, I know speed but does that really matter, I need it because its cheap and I just want something that will play some decent games, such as CSS, and some new games that will be arriving soon. Thanks for all the input, I'm looking forward to all the info ~Justin
