Yes it is going to use more ram, aero takes up somemore and isnt available with home. 64 a gamer preference? Where ? Most of us gamers are still 32, so we can play ALL our favorite titles, not just a few.
Sorry but you are a bit confused here. It's basic which lacks Aero, not home. You must be thinking of 'dreamscene', the animated wallpaper? Aero uses Video ram anyway, not system ram, which is only a problem with shared video/system ram. And 64 plays virtually ALL the games. And 64 is hot as hell with gamers now. Just read up a bit.
