So I'm looking to upgrade my CPU. It used to be fine, and when I got it it was exactly what I needed, but now it's starting to feel a bit old and slow. I have an AMD FX-6350 six core processor with 6 threads at 3.9 GHz, and even running games like CS:GO puts my CPU usage to 80/90%, sometimes higher, even if I close other apps that I wouldn't be using causing me to have significant frame drops, even when I put all settings to low and medium. So I'm wanting to upgrade, especially since streaming or recording most games is not really possible at the moment, and that's what I intend to do. Problem is, I don't know what to upgrade to.
My PC isn't very future-proof;
I have an asus M5A78L-M Plus/USB3 motherboard,
Four, 4GB DDR3 RAM sticks,
NVIDIA GeForce GTX 1050 Ti
and I'm not sure about my power supply
I'm not big with computers, I don't understand most of how they work, but from what I've gathered, in order for me to get a new CPU that would make much of a difference, I'd need a new motherboard that will be compatible with it. And along with a new motherboard, I'd need to get DDR4 RAM, because most motherboards aren't backwards compatible with DDR3. And then, on top of that, I might even need a new power supply because all my components would be demanding more power.
TLDR I want a new CPU, but I don't want to spend all of my money on essentially buying a new PC by replacing almost everything I have. Any help or suggestions would be appreciated.
Edit: if there is no way around it, and the only options I would have for not replacing everything is to get a mildly better CPU without much improvement, I would also appreciate suggestions to new hardware that I can repace what I have with without causing myself to go bankrupt.
