I have a Gateway LT2811U netbook. I have 2gb of ram installed (max the netbook supports). I currently have Starter installed on it, but I have a copy of Windows 7 Professional x64 that I have available. Will 64-bit run well on the netbook? I know it will use more ram than what 32-bit. Will I see any performance gains or is it best just to stick with 32-bit?
