if you are going to do cpu intensive tasks i reccomend the i7-6700k because the 8x operation doesnt really inpact the performance, otherwise the 3930k is a very good option, but keep in mind that the 3930k is a pretty old chip.
Thank you. I was hoping to get one of those 4960x chips at some point as they do float around where I work and go really cheap.
With regards to gaming and benchmarks - would I see a difference in the scores and performance?
I want to make sure I have the best base for my two Titan X.
