Hey guys, I saved up some money and decided to try to build a budget gaming PC, do you have any suggestions on what could I change/improve/replace without changing the price margin by a lot? I never built a PC from scratch but from some googling these are the parts that I thought were the best for my price range. Also keep in mind im from third-world country so prices are actually sometimes higher & amazon shipping fees are stupid crazy, so all my buying is from retail stores & or used.
I'd really like your imput, thanks in advance
SPECS:
RAM: 8GB DIMM DDR4 8GB 2666MHz Kingston HyperX Fury Black CL16 (people told me that I don't need more RAM speed because I don't have high end GPU)
GPU: Sapphire rx 570 Pulse
CPU: Ryzen 5 1600
PSU: Evga BQ 600W (this one hurts the most since its 75 eur but i couldn't find anything that's good enough to replace this one)
Mobo: ASROCK B450M-Pro4
Storage: 500GB HDD (will replace with SSD later on)
Case: TBD
