Sorry if I sound like an idiot or that i have no clue what im talking about but I was wondering if i can upgrade the CPU in my computer to something faster on a budget or at least a decent price, because even when i'm playing a Sega emulator my computer sounds like its going to blow up and on the task manager it says the cpu usage is at 100%. Should I get a new computer or should i just upgrade some of the crap in it? I suck at this so some advice would be awsome.
