I haven't tried overclocking yet, but I plan to. I heard it goes to about 3.2ghz and above it's unstable. I had a core2duo e6400 2.13ghz and when I replaced it my performance sky rocketed. before I could play Crysis on all medium at 1024x768 (no AA) with 40fps average, but now I can play it all on high (with no AA and medium shadows) at 1024x768 with 45fps average. worth the $80 it cost me lol.
