you don't really need to upgrade your cpu i guess for a while.
3d mark is a synthetic benchmark and doesn't reflect real world performance ...
you won't lose that much fps because of your cpu (i guess) at least for intel if you have an i-core (5or7, gen doesnt matter).
but when time comes where you can't keep 30fps on your 1080p games and details already at lower medium it might be time to upgrade.
but most likely an upgrade for a better gpu would bring more fps for the same money ...
cpu would boost maybe from 90>110fps or 25>30fps at best, but a gpu can double your fps ...
for gaming that is. but if you want to stream on twitch, encode videos, cad, compiling, photoshop or other cpu intensive tasks then its time...
hell i would even go that far and claim that your cpu is not slower than what the ps4/xbone have to offer ...
