if your wondering about perfromance. at the moment there is little difference. however there is nothing that takes advantage of pci-e. i believe the main thing with pci-e is that it is full duplex, meaning traffic (data) can go both ways at the same time. versus agps one way street. ... but dont quote me on that.
