Need an advice upgrading my system

[Modestas_1]

Hey!

I've build my computer about 3 years ago and it's wasn't really high end even then. Spent about 600EUR for everything.
I always had problems with PoE's framerate and am kinda ready to start fixing the problem by changing some part of my system. Not sure what it might be lacking to there's where I'll need an advice of you guys

My current gear:
CPU: AMD FX-6300
GPU: Asus R9 270x
Memory: 24GB of Crucial 8GB DDR3-1866 DDR3
Mainboard: Gigabite 970A-UD3p
Storage: Sandisk Extreme 240gb SSD for programs and some WD 1TB HDDs for everything else
OS: Win 10

I just made a benchmark test at www.userbenchmark.com and this is what are the results:

Was thinking about some cheap GPU(I'm low on budget). But when compared some of the budget GPS of today like AMD Radeon RX 460 or 480, there's not that much diference from what I already have.
Recently I started streaming Path of Exile on Twitch via OBS. I can see it eats CPU big time but in reality that doesn't affect game's performance that noticably.
May the CPU have that much impact on the game's performance? I'm kinda confused.

That is a pretty giant difference

Will kind of show how the bottlneck works be it cpu or GPU.


Your best bet would be something like a 7500/b250 motherboard/16gb ram up front. Save a bit more and buy a new GPU later

So I decided to overclock my CPU and managed to do that from 3.5GHz to 4.8 seemingly stable.

This is what I get now:

Will see how it goes in practice
