Looks good except the RAM, it's slow and the Athlon64's like fast RAM. I just ordered a new system yesterday, very similar to your new one, I can't wait for it, after 5 years with this sucker, it will be nice to have a new one.

Good choice on the chip(939) and motherboard(Abit), I do suggest faster RAM though...Btw...make sure your 939 processor has a Winchester Core (Runs cooler).

Athlon64s need at least PC3200 ram (at 400mhz) to run at full speed. This is because the FSB runs at 800 or 1600mhz at a 2x or 4x multiplier.

Correct, well sorta, the socket 754 Athlon64's have a FSB of 1.6GHZ, while the socket 939 have 2GHZ FSB.
