Basically, I have a new gaming PC (that hasn't arrived yet) and was just wondering what upgrades I should do to it when I have the time (and money). It's main use is gaming, and perhaps some day streaming. I never overclock. This is out of pure curiosity since my parts knowledge is as shallow as a puddle.
Thank you
