In all honestly I find that people are just better off with just saving thier money toward a new rig as appose to holding onto the AGP bus.
I can not justify the price tags of a lesser powered AGP video card over much more powerful PCI-E Card that at the same price.
Classis example is this as I work at computer shop.
Both PCI-Express 8600GT 256Mb and AGP 7600GT 256Mb are at the same price. And that is not the mention some of the XFX GF 7900 APG cards which are riduculously priced.
AGP is dead. The extra money spend on APG is better off being used to save up for a new system.
