Intel Q6600 Quad Core @ Hardware Logic
“It’s a difficult question, but certainly a valid one. Those looking for the best VALUE, I’ll usually recommend either Intel’s E6850, featuring two cores operating at 3.0GHz on a 1333FSB, or Intel’s Q6600, which offers four cores operating at 2.4GHz on a 1066FSB. Both the E6850 and Q6600 are available at most retailers in the $270-300 range, making them a great balance of performance and price.”
