Hi, I want to upgrade the processor and graphics card for my Studio 1737 Laptop. Im not too sure what to get at the moment and am wondering do I just buy any or do I need to get specific ones that will work with it? I would like to play new games, like Battlefield Bad Company 2 and other high demanding games.
My current graphics card is ATI Mobility Radeon HD 3650
My current processor is Intel Core 2 Duo CPU T6400 @ 2.00GHZ (2 CPUs), ~2.0GHz
Any help would be appreciated.
I would probably like an Nvidea card because I hear they are better but anything helps

Thanks in advance.
