Really appreciate the long response, genuinely not being sarcastic or anything.
The 9700K overclocks, and runs fine on my old coolermaster, which was a £14 cooler, currently have a H115i Pro, which does a better job, obviously.
When I Google 9700k it shows that the ones from Raimforest UK, coming from Rainforest US (inclusive of taxes) are still available for the £324, so the prices are still the same, and again a cheap cooler would be sufficient to get a decent overclock at reasonable temps.
The other thing that a lot of people willfully omit is the fact that those with 1440p monitors aren't likely running at 60hz, so those extra frames do count.
I was hand on heart hoping that AMD would skin Intel for gaming performance, so I was disappointed with performance, and from a gaming perspective, I really couldn't recommend anything else.
