I plan on using it for some gaming while on the train to work. That being said, is 2GB of RAM enough? I plan on playing games like Starcraft 2, Dragon Age, Call of Duty, etc. I'm okay with low to medium graphics setting on these games, as I just play single player. Does anyone have any experiences they could share? Money is a factor and I'd most likely grab a refurb, which for the most part, only have the 2GB models. Thanks!
