You know, if you picked up a discarded pc and maxed out its ram you would probably be good to go. I do that all the time. They’re usually perfectly good computers. One I picked up just needed defrag and now works fine. I use that one for my CD collection and its connected to my stereo (never have to touch CDs again).
Yeah, about the only reason to get the newest/fastest stuff is if you’re going to play the newest games.
