I wasn't sure if i should post this thread in apple hardware or windows so i decided windows.

I'm running Windows 7 on a Macbook Pro.
Intel core 2 Duo
2.26 GHz
1 processor
2 cores
3 mb of Cache
2 gb of memory
1.07 GHz bus speed.

My question is that I'm considering buying Fallout 3 on Steam and I'm wondering what framerate it would run at. Maybe not framerate but just general speed. Would it be fast, slow. I know there minimum req. on steam but I trust you guys more.
thanks a lot
