I have a Gateway 450 which I bought several years ago. It was top of the line at the time, and I have since upgraded it with an 80 GB hard drive. I don't play games much, but recently got a present and was unable to try it because it required a 600 MHZ minimum and a video card with at least 32 MB. I upgraded the video card, but thought the game would just run slow - no luck.
I don't need to play this particular game, but was wondering if I would notice other benefits from a faster CPU, e.g. is there a Pentium III - 1 Ghz? and how hard is it to upgrade?
