Re: Has anybody ordered here and is it worth it?
I wouldn't bother with aftermarket cooling. If I were you, just stick with stock cooling unless you want to do some heavy OCing.
The GOStepping is just a new revision of the Core Duo or in your case, the Quad Core line. It's better and yes, you should get it. Low voltages, cooler, faster, more OC friendly, etc. Although I've never heard of that website, it looks ok. I would just rather go with Newegg.
