OCZ DDR2 PC2-6400 FlexXLC Edition looks outstanding. It offers CL 4, 4-4-4-15 timings at 2.0 V. The company even tolerates you clocking it at 2.2 V.
The package includes 2x1GB memory, and it should come reasonably priced. It is expected to be available it shortly.
The company also announced 1 KW ProXStream PSU and this one should be provide enough power for all the quad Cores and Quad FXs you need. This baby can do 70 amperes in four independent 12V rails and this is more than most people will ever need.
The company even showed a 2KW PSU at CES - a real stunt product. µ
