i was wondering which is better intel 3960x, 4960x, or 3930k
Depends on your use case.
Before I start- I'd recommend you ignore the extreme series, the price to performance ratio isn't great, and the 4930k which is half the price, is only at the most 5 - 10% slower.
If you're editing (professional video, photo editing, etc)- go for the 4930k or the 3930k. (I would go for the 4930k, unless the 3930k is a bit cheaper)
If you're gaming however- go for a 4670k- that's one of the best gaming CPU's, and isn't overkill at all.
