I managed to pick up a QX9650 w/ a P5E WS Pro, an 80GB G2 SSD, 4GB DDR2, a GTS250, and some IBUYPOWER case/psu for $125 today. Its basically a system that isn't needed, but for the price I figure i couldn't pass it up. I want to use this thing as a headless home server since the P5E has 8 SATA 3gb/s. ideally, the system will be idle most of the time, except maybe for some streaming and backing up of my current systems at home. i want to downclock this thing to about 2GHz to save some power, i want to know if anyone of you think that downclock it will cause stutters in streaming or problems with backing up. i think the highest load it'll have is maybe 2 streams from it at once. It will be wired so i dont think lan speed will be a bottleneck.
