Thanks for the replies. It's actually for my son. He doesn't NEED it. KSP is his main entertainment so I'd like to upgrade his computer. Unfortunately, the budget is coming into play. If we wait a few months we could scrape together more.
My thinking on my build was the proc with the integrated video would save some money but I could upgrade the video later if needed. The one stick of RAM was also chosen with adding another stick later. From what I've read, the processor is more important than the video card. Am I on the right track?
