Could be worse, My 6 month old 940 can't even touch 3.6, it needs 1.5v just to hit 3.5, and even with my giant Sunbeam CCF 120 hits 70* under Prime at 3.5
My Phenom II X4 940 does 3.4Ghz @ 1.325V, 3.5Ghz @ 1.375, 3.6Ghz @ 1.425, 3.7 can't get into Windows under 1.5V and even 1.55V crashes Prime95 in under a minute.
I've been thinking of replacing an Athlon II with a Phenom II, but with so many higher clocked Phenoms out I've been wondering how well the 955 clocks, but it seems to be just as good as a 970 which is promising.
