I recently built a my first computer 1 year ago and am looking to upgrade a few parts. I have an i5-8500 3.00GHz CPU, 16GB of RAM(DDR4) with a speed of 2133MHz (CORSAIR Vengeance), a SSD with 1TB, a HD with 2TB, a GTX 1050Ti GPU, MSI Z370 Gaming-Plus Motherboard, a Hyper 212 EVO CPU fan from cooler master (really hard to put on), and a Corsair PSU RM750 (I think). I don't know where to start, I was thinking to upgrade my GPU or my motherboard because my motherboard doesn't have wifi (going to buy a network card). I don't know if one of my PC parts are holding back another. Have 2 case fans. Using it for Gaming, CSGO, League of Legends and Fortnite. Any ideas? Thanks
