Re: PCI-E Video Card Question?
How the best videocards now are proberly in this order from best to worst : 8800Ultra, 8800GTX, x2900XT, 8800GTS. You got DDR2 memory but it won't matter the videocards will work. The videocard best for your money if you got unlimited is proberly is 8800GTX. If you wanna spend at least as possible go for the 8800GTS 320MB which is $300 but it can still run a ton of games with high settings and good resolutions. x2900XT 512mb fits between the 2 videocards, for the ATI fanboy or your just in that price range of $400 and with a HDMI slot for your HDTV.
Your also gonna need a better power supply for these high power videocards.
