Do not upgrage your computer without playing first...
Mobile 2500+ running 210 FSB at 2000mhz
...usually run at 2500 but the summertime is too damn hot.
I'm running the game with full eye candy at 1024 with 2x antialiasing. It's not blazing but I'm seeing about 20 frames. I know what your thinking must lag like crap but actually it is very playable and it looks soooooo pretty I don't want to turn it down. Every once in a while it will hiccup but very forgiving based on the gameplay overall.
My point is DONT UPGRADE until you've played this game because if my system runs it fine then all you 9700 pro and better vid owners should be all *shits and giggles* when you see this
