Intel BX80557E2140 Pentium Dual-Core E2140 1.6 GHz 1M L2 Cache 800MHz FSB LGA775 Processor

Highly overclockable, From 1.6GHz to 3.2GHz no problems. That's a 100% overclock. 30c idle, 50c load, very cool.

E6850 is selling for $275 and this $70 CPU will outperform it when OC'd. It is a Core 2 Duo Conroe chip. Enjoy.
Amazing budget chip, This CPU is absolutely amazing. I installed it fairly easily into a MSI 650i based motherboard. Idle temperatures where under 30C when checked in the BIOS. I was able to easily over clock it to 2.66GHZ, a 66% over clock, by simply boosting the FSB to 1333, no voltage changes needed, on stock cooling. I'm sure I could hit 3GHZ if i wanted to mess with voltages and RAM timings.
