I have a PC, it's not any late models and should be up to standards, but it runs games like a bitch, have a whole 3TB left and it barely runs =_=
storage space such as the C Drive, it does not matter how massive they are, they don't really control or run anything, they store information
CPU, GPU, and RAM are your computing parts, CPU does all the thinking, GPU is like a CPU but it's specific to graphical stuff, RAM stores active memory from the CPU, this allows the CPU to process things without being bogged down and freezing
