keep the 950 from what iv seen the 2600 is about 10-15% faster then a i7 clock for clock but it would cost about 200 more to get time you get a good board and the cpu and have to try to sell your old gear.

The whole fun of OC'ing was trial and error. What fun is it to press a button and have 4.5ghz. I'd like to know what works and what doesn't work.
