Yep, should run, I dont know nvedia cards but the rest should work,
Im running it on a similar rig and im not running the game on minimum settings.
Intel core 2 duo 3.0ghz
1gb drr2 ram
Radeon Sapphire x1095pro
its not the best or smoothest running program I have but its playable, it a little stuttery, heres a screen shot
so you can see what it looks like.
Click for bigger image, The number in the top right of image are my fps, as I said not great but playable
with the right ingame setup.
Hope this helps
