Currently I have a gigabyte 1070 paired with a i5 6600k and a z170-A montherboard . I just bought a new 1440p/ pg279qz monitor and am waiting it’s arrival. My question is, would it make a huge difference if I upgraded my cpu to the new i7 and left the 1070? Or would it be smart to upgrade to the 2070 and leave the i5. I can’t afford both at the same time. I’m just a tad worried that my current set up won’t preform/ keep up with the new resolution and 165hz refresh rate. Thank you!
