I honestly think the guy should have either saved a couple of hundred dollars and got a cheaper CPU to bring the price down or spent the saved money on a 1070 to give a clear performace difference and hit a rock solid 60fps. I just think if you are spending that much on a PC you shouldn't bottleneck the performance like that. Though it could be the case that he doesn't want to have to bother upgrading the CPU again and decided to splash out now and take a hit. However, comparing systems 'as-is' I think it's worth taking the lavish price on that CPU into account.
(I'm a very poor person though, so while being part of the PC gaming master race, I am one of the mid range PC owning lower castes who just does menial tasks while my people soar above me on i7 processor spaceships I can only dream off) :P
