Things that have been replaced: Mobo, CPU, Gfx Card, and PSU.
I'm going to take this new proc back into the shop I bought it at and get yet another one, and I'll be sending out my vid card today for RMA...
I also need to stop by Lowes or somewhere and pick up another multimeter since I can't find mine and test the rails on this PSU to make sure that's not what's causing the CPU's to blow on boot.
