Finally picked up a EVGA GTX 480 from Microcenter. It even had a $30 rebate until 8/1/10. This card is fast!
Idle temps are around 40 and it's just as loud (or quiet) as my 285. I do notice the fan ramp up during a heavy GPU game, but it's not that loud at all. I have an Antec side 120MM fan in my Antec 900 drawing in air and blowing right on it. I put my hand behind it and it's pretty toasty back there.
My bios is: 70.00.21.00.80 which seems to be the norm.
