Well let me make it clear about what I like to do (sort of)
Obviously I play games. But, I do alot of encoding like video stuff. I PLAN to do alot of rendering in the near future (like 3D Modeling). I also fold too.
Im a mixed person, I do a little bit of everything. This is going on a 680i EVGA A1 board btw.
From looking at the above, it seems the Q6700 is a better choice unless someone can persuade me otherwise.
