Which Video Cards should i use?

EVGA 8800GT



EVGA - GeForce 8400 GS 512MB DDR2 PCI Graphics Card



EVGA egeforce - 8600 gt 256



don't know much about graphic cards but also what's the difference with pci and agp?|||First of all AGP is older slot on motherboard for graphic cards...PCI is newest and faster slot....all new graphic card's use PCI-E slot's..anyway 8400 is worst in this case...8600 is middle and best is 8800GT...also is most expensive...so go 8800 GT if you have money for it :) is best :)|||I would definately suggest to buy EVGA 512-P2-N738-LR GeForce 8400 GS 512MB DDR2 PCI-Express Graphics Card
