I have an old e4300 overclocked using the pin mod. Using a piece of copper tape, 2 of the pads on the backside are connected giving you an extra 33% overclock without affecting the memory or increasing the voltage settings. Works great. I picked up the cpu already modded for $60 awhile back on one of the hardware forums. Probably the best deal is the e7200 combo for $119 at Fry's, if you live near one.
