Intel i7-7800x or i7-7700k

[DJPUP]

I currently have an Intel i5-6600k with an MSI krait gaming Z170A motherboard and Ive been saving up recently to be able to afford a worthy upgrade. I have about £600 and would like to get the best quality CPU (and motherboard) for that price. I’ve done some research and found that these CPU’s are the best “bang for my buck” but I can’t see a major difference between the two. Plus if I was to get the i7-7800x, I was thinking of getting the ASUS strix x299-e gaming motherboard as it fits the budget pretty much perfectly and looks really good, but I don’t know which board to choose if I was to get the i7-7700k.
Pls help

An 8600k is definitely better bang for buck than a 7700k. Its faster at a £50 cheaper price.

6 real cores trumps 4 real cores + 4 fake cores.

In ^^ those tests the 8600k wins even on HTT friendly workloads, on non HTT friendly workloads it will decimate a 7700k.

Cannot find the page now but my 8600k is about 55% faster than a 7700k on intel's AVX bench (non HTT friendly).

Try not to get won over by the i7 branding that people seemed hooked on.

If I was to get a coffee lake prossessor, would it be worth getting an i7-8700k instead as it’s got more threads and can run slightly faster. Also would I need to buy a new motherboard as it has the same socket type as the one I have now?

Yes a new board is needed. If you can afford the 8700k then go for it. Typically you can expect the extra hyperthreading to give it another 2 years of life before obsolescence.

Alright nice one. Thanks for your help
