Personally at this point I wouldn't buy a dual core unless I was on a budget, and there is no way I would even consider an Intel 8XXX series, they are way to expensive with so many X4,X3, and C2Q in the same price range. I'd personally go with the quad, it may be slower in single/dual threaded apps right now, but it'll be much faster in multi threaded apps and multitask much better. It'll probably become the better chip for gaming within a couple years too if you don't upgrade again before than.
