I'm going to say that it's a pretty safe bet that your power supply is inadequate.
That having been said, total wattage is not the best measure of whether or not your PSU is up to snuff. The total amperage on the +12v rail(s) is. A 3870 is probably going to require at least 28-30 amps (this is a guess, but I believe it to be accurate), and I seriously doubt that that 360-watter can deliver that kind of juice.
One other thing about your hardware configuration: you should go ahead and get 1 more GB of RAM because running with 3 DIMMs (or 1 for that matter) as opposed to 2 or 4 is preventing your memory from running in dual-channel mode. This hurts performance.

Fix their home team score on the board to the debt clock, they can win every game 17,000,000,000,000 to 24. Losing team gets taxed by the IRS 100%, then droned."
