Why would you need a new cooler? What do you have in mind?
Also I don't think your problem is fixable.
GTA V simply shits the bed whenever it's CPU limited.

As you can see while the 6700K is happily chugging along at 80 fps the 6320 (at the same clockrate, just half the cores) drops to an average of 20 fps with lag spikes equivalent to 3 fps. I don't need to explain that it does not make sense for a CPU that should be exactly half as fast to drop to 1/4th to 1/20th of the performance.
This is just GTA V being a broken piece of shit.
The solution is to either get a slower GPU or simply cap the fps.
If you want to replace your CPU anyway and not overclock your options are limited. I'm going to list base clock, all core and single core turbo for all.
i5-7600: 3.5, 3.9, 4.1 (your current CPU)
i5-7600K: 3.8, 4.0, 4.2
i7-7700: 3.6, 4.0, 4.2 (more expensive than the 7600K and the extra threads do nothing for GTA V, if anything they cost a few fps)
i7-7700K: 4.2, 4.4, 4.5
For everything else you need a new motherboard.
i5-8600: 3.1, 4.1, 4.3 (note the lower base clock, again the extra cores do nothing but at least they don't hurt you)
i5-8600K: 3.6, 4.1, 4.3
i7-8700: 3.2, 4.2, 4.6
i7-8700K: 3.7, 4.3, 4.7
i7-8086K: 4.0, 4.3, 5.0 (at this point you'd have to go over budget to afford the mobo)
i5-9600K: 3.7, 4.3, 4.6
Notice that your best case scenario is ~22% for 500$, but it won't fix your problem anyway.

Either you figure out how to read the actual model names instead of going by colours or I don't see you successfully ordering one anyway.
You should not compare SSDs by brands or colour, because the speed depends on the model aka what's inside the case, not on the colour or brand logo on the case.
