@rollingzeppelin Agreed. Although a bit old, this advice from Rock, Paper, Shotgun still holds true:
...the [£160 i5] 2500K sports four cores based on precisely the same architecture as the £850 Core i7 3960X and running at a similar 3.3GHz base clockspeed. And four cores is all you need for gaming, now and for the foreseeable future. Critically, the Core i5 series doesn’t have HyperThreading. For gaming, that’s actually a good thing since today’s software can’t tell the difference between a real core and a virtual core conjured up by HyperThreading. The danger here is that instead of running two intensive threads on separate cores, you end up running both on a single core. And that will kybosh your frame rates.
