Is it better to wait for 8700k or go for 7820x in terms of hardcore gaming ?

There is no trustful release date for 8700k and I am leaning towards 7820x. One question I have is would the motherboard with X299 chip work with 8700k in future if I decide to purchase 7820x right now?

I've no doubt they will be clocked the 8700K just high enough to defeat the R5-1600 and R7-1700 in whatever is necessary. Defeating the 7700K in gaming, however, will most certainly need sustainable turbo clocks across all cores of at least 4.2 GHz...; the single core boost of 4.6 GHz or whatever they are targeting will likely prove inconsequential except in some narrowly focused brag-worthy single-core oriented benchmark...

If the 8700K OC's across all cores to 4.5-4.7 GHz (probably at 140+ watt TDP so clocked) at nice moderate temps of 72C or below, a handful of folks will look at it certainly...

I just wish they'd deliver the darn thing so we can see what it will/will not do...

No, the motherboard definitely would not work with an 8700K. It's a different CPU socket.

For gaming, the 8700K will almost certainly be the best thing on the market, but not necessarily by a wide margin. It'll likely also be better value for money than what Intel currently has available, but again not necessarily by a wide margin.

Whether that's waiting for is up to you.

I don't think socket is the case. Coffee lake is still 1151 but chipset requires 300-series which means the current MB will not support coffee lake.

Coffee Lake, including 8700K, is LGA 1151. X299 and the Core i7-7820X is LGA 2066. Definitely not compatible.

AMD will support AM4 until 2020. Just pop in a new chip.

7700K is fastest barring the stupid 1-2 fps lead the 7740X takes on the $400 X299 *if* well cooled up to 5.2 GHz or so....

For stock use, the issue seems to be will teh 8700K even surpass it? And even if it does...does the 7700K then suddenly struggle and feel slow if some 6-core suddenly outframes it? Doubt it...

I know what CPU will NOT outframe it UNLESS also streaming...any R5-R7 yet made...

Why the 7700K is left out of the discussion is actually odd...

Going by the leaks, the 8700K should be strictly better than the 7700K - slightly better singlethreaded performance, considerably better multithreaded performance.

It will beat the 6 core 1600 through turbo boost and higher clocks, but there isn't any benchmarks showing that it will beat the 8 core variants. Bench marks showing 30-40% better multi-threading over the 7700K at around 1050 multithread is what I've seen. which puts is roughly 1450ish depending on frequency.

I did see a leaked test where it did beat the 1800x also. But it could be a cherry picked benchmark for all we know and we will have to wait and see when we get some official benchmarks going.
