upgrade from i7 920 @ 4ghz

[masterjin]

I know my cpu is still good. But having same pc for past 5 years, i can't resist anymore.

1-Skylake 6700K

2-Haswell-e 5820K

about same price for cpu/memory/mobo, about same oc 4.5-4.7, similar performance but more core for future-proof?

What would your pick? with dx12 games on horizon would haswell-e be better option?

If your board supports Westmere then you have more cheaper options.. this is the Westmere Xeon X5660/ 6 core/32nm that cost me $100

This shows X58 running the Xeon at 3.9Ghz does not bottleneck the 290x ..

Yeah, I'd go the cheap Westmere if that's an option (will hold you over until Skylake-E is available), or barring that I'd go 5820k. Average 5820k overclock is around 4.3 on air:

Might as well go with the 6 core option (especially if you have a Microcenter near you). The 4790k was only a viable alternative when you had to pay double for DDR4, but now that that's disappeared, I'd recommend Haswell-E!

As long as you're not a hardcore 120 Hz enthusiast, I don't think you'd miss the small single-threaded performance increase with Skylake.

And it will still give you a massive single-threaded performance increase with Haswell-E: I'd guesstimate about 40% faster at 4.3 GHz.
