hi folks- I've recently downoaded games such as simcity 4 and spores and they are so slow! but the air has 2gig ram, so i am puzzled. could it that be that i have only 5 gig left in my HD? Could that be the reason? Especially simcity should work fine as the minimum required configuration is a G4! Any help much appreciated, my problem only relates to games. Also some overheating, but i guess that's common.
