Best value i9 for multithreading. the i9-9980X is an extra 700 pounds for an extra 4 cores! - just not worth it. i9-9960X performs only marginally faster than i9-9940X. when looking at the hard tested metrics. Still expensive though, and much cheaper in the US. Not fair that UK customers always get stuffed by US companies...
