I need a new gaming system, (especially for OzKansas!!!!) but am waiting till January when we should see a decent selection of PCI Express mobos, PCI Express Vid cards, SATA HDs, DDR2 memory, and the new Intel Chipsets out. That will force AMD to have further price cuts on Athlon 64s, and should create some very good price/performance systems.
I never buy cutting edge stuff, and this is a good time to wait for the inevitable price reductions on all these new standards.
