That build look pretty good, but a few suggestions:
Can you afford to get an SSD? It doesn’t improve your FPS, but it hugely increases loading speed of OS, programs, etc. No other PC upgrade will give you as big a performance boost.
Also, is there a reason you’re using a Nvidia GPU with a Freesync monitor? Either get a G-sync monitor, or an AMD GPU to take advantage if their respective adaptive refresh rate techs.
Do you need the ASUS sound card? Onboard sound has improved a lot, and the MB you linked is decent. You can get better sound with a dedicated sound card, but most people don’t notice that small improvement, especially if paired with lower end headphones or speakers. And if your aim is to get audiophile levels of sound quality, you should be looking at serious audio gear (i.e. external DAC and amp) instead of a gaming grade sound card.
Finally, you may be able to omit the wireless card too. Depending of the setup of your home, or if you live in an area with lots of other wireless networks (apartment complexes) wireless ethernet may introduce lag or contection stability issues… wired ethernet is always preferred when possible.
