I have a Hp Pavilion with a 4.2 score, AMD Turion II P560 Dual-Core 2.50GHz, 4gb ram 300 gb storage, and a AMD M880G with ATI Mobility Radeon HD 4250. I can play games like minecraft well on High performance and HD, 3D graphics but I want to play more games like Battlefield and Black Ops, MW2 MW3 -Beta. I use Game booster but it only seems to end my processes, how can i run my laptop to be faster for gaming without lag?
