Macbook 2GHz Core Duo, one of the early ones, I think it's Second Generation, I forget
And my pride and joy, the Mac Pro, not the newest generation, the one before, Dual Quads, don't have it handy, so I can't give you the speed. nVidia 8800GT
That one is for the games and rendering etc. Main machine, the macbook is for when I'm at uni or home for holidays etc.
