The central processing unit (CPU) is probably the most important part in the whole computer. This is what people classify as the brain of the computer. It is what does all of the calculations that any program needs at any time.
The CPU I chose is the same one that I currently use in my computer. It's comparable to the CPUs used in consoles, and it has four processing cores, which I would say is the minimum needed for any gaming PC.
Is it the best CPU on the market? No. Is it the best for the price? I would definitely say so. The only issue I have run into with this bad boy is cooling, but that is my own fault and something I will get into on the next slide.
