hi! I've ordered imac 27 with 4670. however while i wait i tried in a toshiba with 4gb of ddr2 800mhz and with ati radeon mobility 3650. the game didn't run very well at medium details, i'm not a gamer guy so if i can't play it it won't be a problem, however i love this game in my psp and i would like to ask for someone to try out this game for me with 4670 256mb. i wonder how much better is this graphics, but i'm not expecting too much. so if you have the time, i would be thankful knowing that
