^^maroon is right^^
3.2 or so is gonna be about the max you (or at least I) can get out of a 3600.
its in the neighborhood of the STOCK 6600, but i dont think it can outperform it in too many applications.
a 6000 would be a better challenger as far as benchmarks, super pi, and most applications.
but, for 65 bucks...anywhere in the neighborhood is good.
