775 is such a degraded socket anymore that it isn't *really* worth looking into. I have 3 core 2 machines I use daily (one quad, 2 duo) and the quad almost keeps up it i7 machines (heck, a nice OC i5 passes it up too...) If you are really looking the, the Q9400 is probably the best Bang-for-buck 775 at the time being. It overclocks well (even with a locked multiplier, but you have plenty of headroom) and puts up a darn good fight when running intensive jobs. If you are looking more in the duo range, I've had the best luck with an e6750 machine. I was never quite satisfied with any of the newer Intel duo's when compared to the 6750. OC's well, stays cool, and is stable as a rock through all of it.
