I have a core duo MBP with 1 GB of RAM (2x512MB)... it runs fine, but when I play some basic games (flightgear flight sim, other games of similar requirements), all of my RAM gets eaten up, and when I go to load safari after playing, things are very slow. should I get more RAM even though I only notice slowdowns after playing games? things run reasonably well when I have ichat, safari, pages, and itunes open, but I can't do more than that. even though I wouldnt need the extra GB all the time, is it worth it? after playing the flightsim, my page in/out: 466,143/436,238 if it is worth it, is this what I should get? http://www.newegg.com/Product/Product.aspx?Item=N82E16820148086 any advice would be greatly appreciated. thanks!
