So I went to Best Buy and was told that a Dell intel core i5 processor desktop with 12GB of memory, 2TB hard drive, and an operating system of windows 8.1 for $600 is good for gaming and school use. I asked my friend and he suggested building one would be cheaper and I could build a better one.So do I build one or buy one? This is my first time getting a PC so I'm not too sure what to do.
