I basically need a CPU upgrade now, and if I upgrade to 939 or some other socket, I'd have to add the cost of a new motherboard (probably around $150) to that $200 and then I'd want to switch to PCI-E, which would mean a new video card, so add on another$250 or so for a decent card. All of that to add PCI-E and dual channel doesn't seem worth it at the time.

The new CPU is basically to hold me over until that next generation comes out. Then I'll wait for those prices to come down.
