Missed getting the 8700k by two minutes but I did get a 8700

It's already pretty expensive at 409$ Canadian (the 8700k is $499 Canadian) And I hear they are running pretty hot so to OC need fairly expensive air cooler or water cooler which I originally didn't want (first solo build) so probably saved myself around $125-150+(I would still put a cheaper cooler on the 8700) But I still have to buy a z370 if I don't want to wait which I don't mind so much. I've never OC before because I didn't really know about it but I have a older capable pc.... so how much performance am I losing... is it really that bad to have the 8700 which is locked at one core 4.6 all core 4.3 I believe but base 3.2. Also how does it interact with auto tune type OC does it still optimize my pc other than the CPU with a locked chip??

Everyone reviewing 8700k and I'm not sure the real difference in performance. Thoughts?

Versus the stock 8700k there wont me much of a difference. However an 8700k at say 4.9-5.0ghz on all cores will outperform a stock 8700 by quite a bit depending on the application.

A Z370 board will allow you to use DDR4 faster than 2400mhz, I saw a video comparing a locked i5 8400 with 2400mhz ram to one with 3200mhz RAM and the 8400 paired with a 3200mhz ram was performing quite a bit better in almost every test even games.
 


Can you link to that video? I would like to see it and also have it for reference to tell others. I saw same thing in a Digital Foundry video with a stock i5-7600K performing as fast as an overclocked 7600K, only difference was RAM speed.

It was actually the i3 8100 in this test, but I would imgine the i5 would show similar results maybe even a larger difference. It seems to scale with CPU overclcking, so the higher you clock your CPU the faster you need the RAM to be for it to actually show a sizable diffrence in many applications.

I think its greater than 10fps from 2400 to 4000 (z370 mobo seem to do 4000) I was wandering this too and cant believe not more discussed for 7700k... everyone says if you're getting locked cpu better to pair with cheaper non OC motherboard. But than I learned you can run the mobo specified ram with the z370 board and going from 2400 ram to 4000 is going to yield more than 10fps I imagine based on video i saw comparing 2400-3000-4000 ram. Why the heck would anyone put a 400+(cdn) cpu on a non z370 board with 2400 mhz ram to save like 50-100 dollars on a mobo?? especially now that 4000 speed ram is like 250$??

I think cheaper motherboard only applies to locked i3 and maybe i5 (than 2400 or less ram seems more balanced cost wise) and not just a marketing ploy... i think it would be really dumb to put a 8700 on cheaper mobo with 2400 ram
