"1GW of power"
wow how many power supplies do you want? perhaps you mean 1kw?
anyway i can't see why people are so obsessed with hugely expensive gaming rigs. i'd rather spend the money on overall power. so the opteron 280 if memory serves is a 2.4ghz dual core. mmmmm 8 2.4ghz cores, i'm in heaven
. don't know what server boards are like for overclocking or if it is even possible but i would push for say 2.8ghz and rule the world. some server motherboards i believe have pci-e x16 slots but i would settle for one with AGP and just get say one of the gainward 7800gs's with the gt core. but if i could find one with x16 slots obviously i would throw in a 7900gtx/x1900xtx just to complete the rig.
