I am trying to decide on what to upgrade my overclocked Q6600 to, either the core i5 750 or to up to the core i7 930. Price difference is about $300, largly from the RAM, only need 8GB for dual channel, but i'd get 12GB for triple channel. (id get 3 3GB sticks for 9GB total if they made them.)

I read this article, comparing different processors, when clocked at the same rate, and also overclocked, check it out here http://www.legionhardware.com/articl...ormance,1.html

For the most part, all of the i7 and i5 processors seemed to be near identical in terms of performance.

Will hyperthreading and triple channel memory make a big difference?

I already have an SSD and a decent video card (GTX 275), which I'll update later.
