No way. The phenom is a much better CPU. Especially now, since most new games use more then 2 cores.
Exactly. While the g860 is much more efficient, it still only has 2 cores and is slower than the phenom II x4 945.
Speaking of which, if you're in the market for a phenom II x4 945, why not try to get a 955 or 965 Black Edition? They cost a few dollars more and can be overclocked even more (and have faster default clock speeds).
