pci-e just doubles bandwidth and makes the connection multi-directional, as of yet the additional bandwidth and all the features of pci-e are unnecessary... top of the line cards of today don't even max out AGP 8x, so don't worry about this yet, id say it could be 2-3 years before we need the bandwidth from pci-e... and as for the processor AMD kills in gaming, and the p4 wins in multi-threaded apps, but in most daily use they are equivelants.
