8700k vs 9700k for gaming

[atavax]

I have a 2600k and a pci-e slot on my mobo died the other day. Fortunately my motherboard has a 2nd one, and i moved my videocard over. But my mobo and cpu are nearly 8 years old at this point, and this is pushing me towards upgrading my system. Is the 9700k even remotely viable compared to the 8700k? The 8700k should be easier to cool and likely overclock higher with 2 fewer cores; while with the general rule of hyperthreading adding about half a core's worth of performance per hyperthreaded core, the 8700k should in theory have 9 cores worth of performance compared to the 9700k's 8. Plus, the 8700k is $270 at microcenter if i also buy a motherboard there, compared to the 9700k being $400 wherever i look. Am I missing something? It looks like the 9700k is a horrible value.

You're right in the end, the 8700K is slightly better than the 9700K and at the prices now... 8700K all the way at MC with bundle.

That's not true.. It's mostly like 20 - 25% for each hyperthreaded core. 

 

Other than that i would go for the 8700k anyways due to it being a little cheaper, is readily available and there is no difference in gaming clock for clock ....

Might want to consider the 8600k if all you're doing is gaming, or the 9600k if the pricing is similar.
