I also Want it to be upgradable over time

If you're going for max frame rates, then instead of the Ryzen 7 3700X, I'd recommend the Intel i5-10600k. It's going to be better than the 3700X in gaming because of its clock speed advantages. It's the same price as the 3700X, with the only caveat being you'll have to purchase a CPU cooler separate. Personally, I'd recommend the Noctua NH-U14S if it's available. 

The 3700X does have an advantage with two extra cores, but that only matters in situations that can take full advantage of those extra cores, which most games can't do. For gaming, the 10600K is really the way to go. Alternatively, you could jump down to the Ryzen 5 3600, which will perform basically the same as the 3700X, and instead look at upgrading your GPU to an RTX 2080 Super, which would give you better FPS over the 2070 Super. 

Otherwise it's a pretty solid build. I think I'd personally go for an 80+ Gold 650W power suppy instead, like these:

But that's the only other thing I'd look at changing.

My small suggestion is I'd consider if you can afford it could add a m.2 but thats only if you wanted to take advantage of the slot the mb has. Solid build And the other thing to add onto TSTonyV said:

Is that OC (Over Clocking) isn't always worth trying to get into as its really often like 5% or 10%  boost in performance and often isn't worth then the loops and hoops to get a stable clocking it also is running of course your PC parts harder as well. Hence why the last bit about dropping to a 650 W PSU would make sense. Plus a 2070 super is already kicked up a notch to add on to that so its not really necessary to try and boost it further its already going to be a kick butt up tick for general HD gaming.
