"The X4 810 is a nice part which will make quite a few folks happy.
It does not run really hot, it does not pull all that much power, and it
certainly performs well considering the price it is at. In most tests, in
comparing to previous results from the Phenom 9950, it was about 5% faster
overall than its predecessor at that same speed. It does hold 2x the L3
cache as the 9950, and the extra internal tweaks are likely to help as well.
Currently it is one of only a few chips that will fit in AM3 motherboards,
so if a user who is adamant about buying an AM3 platform they have no other
choice if they want a quad core."
