Budget (including currency): A little over 500 USD
Country: Mexico
Games, programs or workloads that it will be used for: Mostly League of Legends, CSGO, Valorant, Overwatch. Other AAA titles will be played (The Witcher, Cyberpunk, Borderlands 3, etc) but not the main focus of the rig
Other details (existing parts lists, whether any peripherals are needed, what you're upgrading from, when you're going to buy, what resolution and refresh rate you want to play at, etc):
I currently have an FX 6300, 16 gigs of RAM and an R7 360. I bought a 144hz monitor and can't get the most out of it since I can't consistently have 144+ fps. I don't earn a lot of money and since the gpu takes up almost half of the budget for the full new rig (since I don't have to buy a PSU or a new HDD) I was thinking of keeping the old GPU with the new CPU, but I was wondering if it'll be better to buy the new GPU and keep the FX until I can afford the rest of the rig.
TL;DR Is it better to buy the GPU first (RTX 2060 Super/RTX 2070) or to buy the new CPU and necessary components (Ryzen 5 3600, motherboard, ram)?
