I'm new to pc building and parts. I have a i5 2500 and a GTX 1050 to 6gb installed on my PC. Whenever I play games I usually get huge lag spikes and the game just crashes. I decided to open task manager to see what the problem was. It shows my CPU using 100% of it's power and GPU using 60. If I want more performance should I upgrade my CPU. If so what is good for a 1155 socket motherboard the is relatively cheap and will give me a big boost in performance?
