I do not know too much of how pci express works but I do like my agp mobo. If i end up upgrading my motherboard/pcu setup... would it be well worth it to go with pci express? or will agp do it? Do i even need that fast of a vid card? Mainly just browse play light games and wow sometimes.. what do you guys think? Should i just keep the current tower i have now and not upgrade anything but a new agp card and ram and vista? i have a xp 64 bit 3000 with 80 gig 10000 rpm ata100 hd.. geforce 6700 i believe... i need to figure out my specs again im at work and my tower is at home so i will figure it out ..
