Hello, I would like to get some advice on PC upgrades. I originally built my PC 5+ years ago and it's a bit of a mixed bag, because some things have been replaced and some haven't. I play a lot of different games but the heavier ones I frequent are Rainbow Six Siege, Mordhau, Dark Souls 3 for example. I live in Germany. My budget is yet to be determined, because I'm a student who only makes enough money to cover his monthly expenses (excluding rent) and need to talk to my parents about it. I'd like to know though what upgrades would result in the biggest improvements. Here's my build:
Motherboard: ASRock Z77 Pro4
PSU: FSP Raider 750
CPU: Intel i7-3770 (non K)
GPU: Gigabyte Windforce (3xFan) GTX970
RAM: Evo Corsa GeIL 2x4GB DDR3-1866MHz
SSD: Intel 330 Series 120 GB (SSDSC2CT120A3) + Samsung Evo 850 500GB
HDD: Western Digital Green WD20EARX 2TB, 5400RPM, 64MB cache
Case: Cooler Master Silencio 550
Cooling: 2 Cooler Master case fans (the ones that come with the case I believe), Hyper Evo 212 for the CPU but with a Noctua NF-P12 redux fan because the original Cooler Master one wasn't working properly after a while (probably the bearings).
Monitor: Samsung 24" S24B350H, 1920x1080, LED, 60Hz
Thank you very much in advance.
