Wait for i7-8700k or stay with i7-5820k?

There are some IPC gains to be had yes, but they're not gonna be that big. Main difference is that his chip was 6/12 on a far bigger die so different cooling characteristics but if he already has sufficient cooling and clocks for the 5820k then getting rid of his expensive chip and motherboard to move over to a consumer platform (which is a move down) is just not a good idea.

Anyone wanting to buy X99 or X299 right now would be a fool since many of the chips will be obsolete vs the 8700k (Not to mention Ryzens and Threadrippers) but someone who already has it? Is not worth putting money down to basically sidegrade.

Yeah, this was my original question, or point of this thread, if you will. I know my setup is an older gen, but basically an enthusiast platform, compared to a consumer platform. That's why I was wondering if it was worth the switch. Cuz I thought about going x299 for "more pci lanes" (depending on the chip chosen, as we've found out). But I quickly realized that it wasn't worth the huge jump in price that Intel is charging for that platform. And I only have like a .2Ghz overclock on my 5820k right now, cuz all I have cooling it is a push-pull config 120mm radiator from Corsair (don't remember the exact model number/name). I would go higher since I have good temps, but it's like 4 or 5 years old now, so I'm scared that the pump will die soon, since it's an older AIO. That's why I want to do a fully custom water loop. That and I bought a Founders 1080ti for the loop reason as well

Sounds like you think your current CPU has 4 cores? It actually has 6

Sorry, you're right. I should have specified. I know it's a 6 core, 12 thread CPU. I just figured that with all the optimizations and features that have come out since my Haswell generation, it would be time to upgrade. But it's starting to seem like my older platform really isn't that old in the grand scheme of things now a days. Lol

How far of an oc can you get?

I'd say skylake/Kaby has an 8-10% ish ipc lead on haswell. And the 8700k might hit around 8-10% higher clocks? Which is around 15-20% faster.

If I were you I would test out streaming first, see if performance is ok or not. And then decide. Though it's worth noting for streaming you may be better off with a 5960x or 6900k. May, I'm not 100% sure depending on how high an 8700k can oc.

The 5820k is also a 6 core 12 thread CPU. You're probably looking at ~10% increase to IPC and a solid few hundred mhz jump in performance. You'll probably get about +15% increased single core performance. Is that worth the motherboard and CPU costs? I'd say probably not. THe 5820k is still a great part. However you don't need to make a decision now. Decide when reviews come out!
