bottleneck

hello, so my pc is getting very bad fps in most games only recently, the bios is updated same with drivers it seems everything is up to date. i just got the rtx 3070 and my cpu is the ryzen 5 2600 “planning on getting a new one soon” my friend has the same and he’s getting like 120 fps in battle...

Hello, so i'm currently having CPU - AMD FX8300 Eight Core and GPU - AMD Radeon R7 370. I'm planning on buying GPU - GeForce GTX 1650 SUPER OC 4GB, but I'm worried whether there would be any improvement due to bottleneck. I need some advice please.
