So I have wanted to do some upgrades to my PC recently. I play a lot of ARK and it lags a decent amount, I have an I5-4690K CPU, GTX 960 and 8GB or ram, I know a portion of it is the game being horribly optimized, or at least to my knowledge it is. But I was wondering if I did want to upgrade my PC what would need to upgrade. I built my PC so I know a decent bit about computer parts and how they work and such, is there any sort of stress test I can run to tell me what is limiting my performance. Like is my GPU maybe bottle necking my CPU some how, is it my motherboard. I don't want to upgrade my GPU or my CPU and have it not make a difference because my motherboard is bottle necking it or something. If by chance I did say something that didn't make sense I would appreciate it if you enlightened me rather than belittled me, I am always open to learn more Thanks in advanced.
