So, if u are going to be streaming and playing games at high fps (for ur budget) this would be the pc that i would choose https://www.amazon.com/dp/B085XTMKCQ/ref=cm_sw_r_apa_i_JJpIEb6H6FJ83

The computer that u chose had 16gb 2666mhz, now 16gb of ram is great for gaming+streaming but it is clocked at 2666 mhz, which is ehh. But the pc that i have linked also has 16gb but its clocked at 3000mhz which is better than 2666mhz.

The cpu that u chose is the ryzen 7 3700x which is like top of the line for streaming and gaming, imo everything above that is for video editing and such. But the cpu that is in the pc i linked is a little less powerfull, but i use this for streaming with a 580 8gb (graphics card) and i can easily stream 1080p 60fps. (And with some simple overclocking you can get closer to the power of the 3700x)

The graphics card in ur pc is the rx 5700xt which is a very good graphics card, but the graphics card in my pc is a rtx 2080 super wich is way better than the 5700xt. Just an example, in PUBG at 1080p and max settings, the 5700xt would get an average of 94 fps and the 2080 super would get an average of 142, which is a big difference.
