i got a 6700k and have absolutely no intention of even looking at upgrades.
If you are in the market for more than 4c8t then yes sure its interesting but really very few people are.
When mainstream stuff starts using the CPUs to their full potential then sure ill jump too.
8 cores for me is a real pull. It'll really speed up some of my work. I know games won't benefit much from it but when I think about how much I play games these days it is hardly worth spending money on a system solely for playing games. I mean I'll get a decent GPU but I'll get the CPU that helps my work the most rather than games.
