Question what should I upgrade/change first? (on my first time build)

Mar 20, 2023
Mostly just playing MW2 and Apex with friends dont need anything super nice but I would like an enjoyable gaming experience....
I'm pretty certain most will say a better graphics card is first on the to-do list but I figured Id get some advice just incase.

Current build is a little all over the place (I mostly used my brothers old parts for previous builds after he upgraded )

-AMD - Ryzen 7 3700X 3rd Generation 8-Core - 16-Thread 3.6 GHz (4.4 GHz Max Boost)
-NVIDIA GeForce GTX 1650
-Corsair RMX 750 watt PS
-ASUS - TUF GAMING X570-PLUS (WI-FI) (Socket AM4) USB-C Gen2 AMD Motherboard
- Ram: Corsair Vengeance RGB Pro 16GB (2x8GB) DDR4 3600 <---( I have 4 sticks total bc I accidentally doubled ordered and it was a pain in the arse to return so I kept them )
