I knew had to switch out mobo and ram, but I've been reading that the new gen processors run quite hot? My current CPU, even though its overclocked runs at 65C the most, even at 100% usage, and I am only using a CM 212 cooler. Will I need to also buy a water cooler for the 8600k? And is the 8700k worth the $100 price difference?
For most part the difference in price between 8600k and 8700k doesnt justify the performance gain. But thats just for now. Lets say, 5yrs down the line, when the 8600k will start to show its age, the 8700k will be still going strong for the most part. So that $100 doesnt give you as much performance as much as it gives you longevity.
As for the cooler, the Coffeelake chips do tend to run hot. But it depends how hard you are pushing and how good you are in OCing. For the most part, something like a Cryorig H7 can give you mild to moderate OC. But if you plan to push something like 5ghz, you will need a bigger Cryorig/Noctua/AIO.
Or, you can simply buy it OCed... https://siliconlottery.com/collections/coffeelake
