I finally got around to installing this on my laptop (see sig), and all I can say is: Damn, I'm glad I went for the 8600mGT.
I'm playing v.1.2 with all settings on medium, and it runs great. This is obviously not enough for most you graphics wh0res, but it's pretty effing descent for your average Joe who just wants to play the game and not have to worry about 16x AA and all that other silly nonsense.
I'm gonna see if I get around to tweaking it a bit to maximize quality, but right now, I'm very happy with the outcome.
