Building setup, any suggestions

Solution
I’ll give that it’s not bad. Try to turn down the monitor to a standard 16:9 screen (probably at 1080p). Some games and apps don’t support ultrawide too well and your gpu may struggle a bit regardless, considering it’s an entry level gpu for gaming. Otherwise...well, it looks ok considering prices of components from the crypto rush

The build looks good, and while I personally love 21:9 and only have had two games not support it (Dark Souls 3 and CS:GO), the GTX 1050 may struggle to give you good frame rates. Also keep in mind future upgradability of the system if you did want to get more graphical power.
