I am mostly happy with my gaming performance.
That's the only benchmark you need, friend.
The 1151 socket is only compatible through 9th gen. I doubt you'd see a performance leap from a compatible socket upgrade, and if you're getting a new mobo, you might as well upgrade the RAM, and now your GPU is the bottleneck, plus you better make sure you have adequate power for it all. Congratulations, you bought a whole new computer.
Intel has gone out of their way to make it harder to upgrade components. You should save up to buy a whole new system when you are no longer happy with your current performance.
