Your title says desktop performance.
Do you really mean gaming performance?

Some games are cpu limited, and some are graphics limited.
To see which, try this test:
Run YOUR games, but lower your resolution and eye candy.
This makes the graphics card loaf a bit.
If your FPS increases, it indicates that your cpu is strong enough to drive a better graphics configuration.
If your FPS stays the same, you are likely more cpu limited.

If you are cpu limited, a typical I7-6700K can be overclocked to 4.5; 4.7 is reasonable:
Your motherboard is one of the best to do so, so all you really need is a good cooler.
Here is one for example:

If you are graphics limited, that is a tough issue to solve with your budget.
