To upgrade or not to upgrade

[Rage474]

Hey folks,

It's been a while since I've last upgraded my PC (2013) which I use mainly for gaming - 1080p for now though maybe higher if the right deal on a monitor comes up. Am starting to feel it a little especially in modern titles - I'm looking at you PUBG (I know it's not especially optimised right now).

Here's my current specs:
CPU: Intel i5-3570k @ 3.4
GPU: GTX670 2gb
RAM: 8gb 1600MHz
Motherboard: Gigabyte SKT-1155 Z77X-D3H

I've got a few older HDDs and a small SSD with an OS on it also. The PSU is quite old...though at 1000W can hopefully handle an upgrade, will probably keep the old Coolermaster case to keep costs down if things fit.

Main question - with these parts is a partial upgrade realistic (and if so what) or am I looking at a rebuild to see noticeable performance gains?

Cheers

Interesting...maybe I'll go that route then. No weird compatibility issues, just a PCI-E slot?

If upgrading somewhere in the region of £200 would be nice.

Great stuff, thanks for the responses guys. Think I'm most likely going to stick a 1060 in and OC the CPU. 3GB vs 6GB is a pretty massive price difference...tough choice, although I wouldn't like to find myself in a years time when I eventually upgrade the rest of the system realising that 3GB VRAM doesn't cut it anymore.

Any solid guides you would recommend on overclocking for beginners ?
