How much of an improvment is PCI-E over AGP? I have a Geforce 6800GT so would a PCI-E Geforce 6800GT be much better than an AGP one?
My specs are AMD 64 3400+, Gig ram, 6800GT at Ultra stock speeds and a K8NE-Deulux MB...I only really play games in 1024X768 Res so would this system hold me out at those settings for a longish time, even without PCI-E?
Would it be able to run games like Killzone PS3 and stuff when those games are released on PC? (ie, during the Next-Gen gaming days)
