I don't do much gaming on my computer, but I've always loved playing Doom since the early 90s. I haven't played it in many years, so I decided to try the free demo version on my new laptop. It's Toshiba Satellite with Vista home premium, dual-core T2310, 1 gb ram, and 1.46 GHz. Doom runs a little too slow as is, so I'd like to know how much upgrading I would have to do. Do you think simply adding another gb ram would do it?
