ok i know my rig is bottlenecked
cpu i7 2600k
gpu gtx 1080 ti
memory 16gb
hdd 240gb ssd
monitor 4k
but the my system runs well anuff for the games i play
and the http://thebottlenecker.com/ says that even upgrading to the best chip my MB (i7 3770k) will take is only 2% better so there is no real point in me going for that plus there still quite expensive in the UK. so my question is what should i do without spending lots of cash ?
