Hey guys I just bought a NEW AMD A10 Quad core at 2.3 gh laptop with 8GB ram and AMD Raedon HD 7660G graphics. When I play MW3 at like 1260x780 it lags at LOWEST GRAPHIC except for specular maps. WHY? Brand new laptop just only game is MW3.

New laptop, and I do not have the skills to take apart any pieces. It was laggy ever since I first turned it on. I disabled services, startup items, but still laggy. PLEASE HELP!!!!!!
