It's been a long time since I built a PC so I could've done a better job picking parts, but I'm satisfied with how much power I get for the price. The RX 570 is pretty good for what it does. I was able to play most games at around 120ish FPS, which was pretty good since I got a 144Hz monitor.
In the future I'd add some more case fans, since during high GPU load, like playing modern titles, the entire case starts to heat up and I only have one case fan that came with the Cougar QBX.
Speaking of Cougar QBX, its a bit plastic-y but dang I love the looks of it
