No no, these are good things to know. As much as any PC gamer will hate to hear this, I'm a Mac guy, so PCs are like a foreign language to me. I just use something I have at the time, which gets me by.
Any suggestion on a prebuilt machine that is going to handle things better? I have zero interest or time to built my own PC, so it would need to be something I can buy on ebay or the like. Generally under the $1000 mark, with HDMI connectivity because my "monitor" is a 40" Samsung HG40NC690DF Smart TV.
