I agree with the first commentor: why? The E8400 is an easy cheap overclocker (if you know what you are doing) if you are a system builder. I have one running at 4.4GHz. However, since you are running things in an OEM box (Dell) stock speed, save your money and don't upgrade anything until you are ready to learn how to overclock, which would require a new motherboard, fan/heatsink, and possibly power supply and better memory than that crap Dell sticks in there. Oh, and FYI, graphics and video encoding do much better on quads than even higher clocked C2Ds. But if you mostly game, you'd be better off with a higher clocked Core 2 since they reach higher overclock speeds than quads generally.
