When i turn on AGS with battery i have (5:00) of battery time. With it turned off i have (5:37) of battery. This isn't that big of a difference. I though this "High end graphics card" was a lot more powerful than that? I have Word open 3 windows in Safari open and system Prefs. Why isn't there that big of a difference, also, is there a difference in clarity in simply browsing safari and using word between the two GPUs? Not flash player or anything just browsing the internet like using MRumors? I have the HD Glossy screen if that makes a difference.
