Had it for almost 5 years to the day and one of the CPU's (dual 2.3ghz) shit the bed. Ain't that some shit. I'm pretty pissed. I had to swap position with CPU2 and use the Apple System Diagnostics disc to run thermal calibration. I expected to get a lot more life out of this thing. Especially since I replaced the nVidia 6800 that crapped out last year. It's a BTO option card so there were few out there and they pull a premium @ $250-300. Debating on getting a 17" i7 MBP now.
