Well, it is DX10, as I fairly recognise it, so a DX10 card is in there. A CPU preety fast, say aDual core helps a lot on that game. As far for a Physics card, any game can do without is, BUT, I'd recommend it for this one and future ones, so yeah.
Whoa, DX10. I wonder if high defintion (HD) video cards will be as good as that? Is there such a thing as an HD video card? I know there's HD tuner cards or something like that. One of the guys at work has one and he's recording everything in HD.
