If you want a curved screen 144Hz and a VA-panel with 1ms respons time than you can look at the 'MSI OPTIX MAG 24C / 27C (24 or 27 inch). they are great gaming screens

its from zotac, the same brand as mine 1060 gpu. GigaByte do also have gpu in that price
i think a 1070 ti would be perfect and the i5 8600k could be overclocked (now on 4,3 GHz) but it would not be a problem with the cooler master masterair cpu cooler?

this psu am i using right now. i think (if it isnt too low) it should be fine
Some games (csgo, rainbow 6 siege, apex legends, fortnite) but also 3d drawings for my work.
but i got 2 240Hz monitors for the fps mut my gpu cant reach it so easily
