The general answer is "do so at your own risk"
The usual caveats are that you need to use a CPU that the systems came with, and be ready for issues if the BIOS doesn't like the stepping revision of the CPU.
If you've already got the CPU, give it a shot, if you purchase then be wary.


I'd also be very hesitant to changing number of cores and increased power draw, both of those would have me stepping back and not doing the upgrade.
