bigtimeballer50, im guessing your talking about PCI Express...? PCI Express will very soon be alot better then AGP. As of this moment, i guess its safe to say PCI Express is a little faster, or would perform better then the same card of AGP. But not by alot. Thats because they havent fully utilized PCI Express. Soon they will, and AGP will be on the out side like old PCI.
