It has taken me a while to ween myself away from the 6600K i5, I know a few people would ask why I have done this... First point is futureproofing, although newer chipsets and CPU's have been announced I still think the 7700K will still be the mainstream CPU in a high end system. As always the clocks you will get from an OC will always be different depending on hardware etc the weakest link will always stop you hitting that golden 5-0, in my case it is my cooling solution and also the CPU heat spreader itself as it stands, there is de-lidding the CPU, would I do it? NOPE... I get more than decent temperatures at 4.8ghz at 1.23V on the ASUS Z270F strix motherboard, the 200mhz isn't worth voiding anything. At stock I managed a stable 4.5ghz turbo on just 1.15v, I got hangs at around 1.12 so just bumped up a few notches and got this stable for 8 hours under real bench. I know this CPU is more for multimedia and production etc but since switching to the i7 I've noticed that the multi threaded games i play have become insanely smoother and the lower end of FPS has been boosted drastically, all the benchmarks I have looked at online don't do the CPU justice while the numbers compared to the last gen CPU may not look massive there is definitely a difference on the eyes. 9/10 +Performance is outstanding when overclocked! +Easy to overclock -Price can be off putting to some -heat is an issue, i would recommend an AIO water cooler or a Noctua NH-D15 MINIMUM if you plan to overclock otherwise I'd recommend the Coolermaster 212X if you plan to run at stock.
