I have a bit of a conundrum. I recently started playing Insurgency: Sandstorm, a notoriously poorly optimized game, that supposedly is quite CPU heavy. I'm struggling to get past 90 frames on medium settings which feels pretty sluggish. However, I can't decide how I want to fix this. I currently have an I5-9600k(which is slightly overclocked) a CoolerMaster Hyper 212 Black, a GTX 1660Ti(which I pushed pretty far with OC), and 16 GB of DDR4 Ram. When monitoring usage during a game, I noticed that my CPU usage was at 100%, and that my GPU was hovering around 80%. My dilemma is: do I upgrade my CPU to something like an I7-9700k and hope that the increased core count will push me over the 144 fps threshold, or do I upgrade my CPU cooler to something like the Noctua NH-D15, or perhaps even watercooling. Is the CPU upgrade worth it? If I upgrade the CPU I will upgrade the cooler regardless.
For reference, I get around 350 fps on native res(1080p) in CSGO on medium settings, and around 140-180 in COD Warzone on somewhat high settings.
Thanks for reading this, any help is appreciated.
