as far as gaming is concerned your home basic is fine. if u want to get more appearance(aero desktop experiance)-that glassy translucent appearance, then go for the windows 7 home premium 64 bit or 32 bit(depends on maximum ram usage).but don't go for the professional and ultimate versions for gaming, as it is a waste of money.also if u want to upgrade, upgrade package frome home basic to premium is available-go for that.
