actually upgrading to PCIe this generation makes no sense. Especially for the intel-based motherboards.
If you upgrade to Alderwood, you get the high cost of DDR2 at performance <= DDR. DDR2 improvement won't be felt until the clock speed reach 667, 800mhz.
2nd, prescott performance isn't drastically better than northwood right now... plus it looks like intel will eventually ditch their netburst tech for something else.
Finally PCIe won't bring any huge improvements immediately, look what AGP 3.0 did (not much).
i'd wait until BTX before upgrading.
