bottleneck performance?

Bloomfield was quite weak and didn't overclock that well. I'm using a 6 core sandy bridge that I have clock at 4.6Ghz, which was quite a jump from previous generation. Newer generations CPUs only had around 10% increments in performance and didn't overclock any better.

I plan to upgrade to Skylake in the fall.

Skylake doesn't even provide that much difference from 4790K. Unless you are referring to Skylake-E (since you are on Sandy Bridge-E), maybe that's worth it.

Ya... I see leaked benchmarks any where from 4-8% or 15% IPC gain from haswell. I'm a little mixed on continuing with -E platform because I haven't seen increase gaming performance switching between 4 to 6 cores, it's expensive to upgrade frequently and it's nearly a year behind latest architecture. DX12 games may take advantage of the extra cores. Depending on further benchmarks I see with DX12 and skylake if I'm not impressed I may wait it out till Skylake-E, which will probably be around 2nd half of 2016.
