i was running 6 cores, a 4870 and an 8800gts full load 24/7 for almost 30 days last month. i think that'd do it? my 4870 uses almost as much power (or right at it) full load as your SLI 8800GTs. i dunno...maybe i ran the heater more than usual lol who knows...
but anyways...rican what do you think of my dilemma? whats your vote?
