i have the 2700+ myself. it's a great cpu, i've had no complaints.
very powerful too, the only thing is that you'll need a pretty heavy duty heatsink and fan. did you order retail or OEM?
if you ordered oem, you'll only get the cpu and nothing else, if you ordered retail you'll get a good cooler.
if you don't have a cooler, you should buy an all copper one, i had the thermaltake volcano 9 (which is part copper part aluminium), and it was letting the cpu run at 64-65 degrees idle. i have scorch marks on the underside because of that :(
