The build mostly looks fine. The only change I would make is to either go to 16GB RAM using 2x8GB sticks or go with 2x4GB sticks for 8GB. The Core i7-7700K uses dual channel memory so you'll lose half of your memory bandwidth using a single stick. As for AMD vs Intel, ideally you'll want an Intel system as they have higher IPC performance which is important for gaming. However, as most games are GPU limited rather than CPU limited, I'd recommend picking up that 2x8GB or 2x4GB kit of memory over an Intel platform if you're limited on funds.
Hope that helps!
