Okay, basically i have the 2010 macbook white. It has an intel core 2 duo 2.4Ghz processor and a nividia geforce 320M graphics card with shared memory. The memory that i have in the laptop is 8gb. I upgraded it from 2. So can i run cod4 with a resonablly high frame rate? I dont need brilliant graphics but would i be able to get around 60 fps? Also, should i get it on the appstore or through Steam on my windows partition? What run better/be better in terms of modding. Also does cod4 on the pc have an issue with hackers? Thanks very much.
