You should be fine except disable dynamic lighting as this will kill your system.
It doesn't look so good but will boost your fps big time.
DONT disable dynamic lighting if your computer runs it playably (25+ fps all the time), disabling it can really kill off some of the immersion in the graphics, and its really worth a slower framerate to appreciate that.
I think a lot of the reason people complain about the graphics in this game is down to having turned off Dynamic Lighting; the terrain detail and parallax mapping work hand in hand with the DL to create some really amazing effects, and simply dont look as good with it off, you lose a lot more than people might have you think, and when you consider all the little details in the lighting (moving detailed shadows on dark walls near fires etc) it really adds up to a great package, its just very demanding on hardware, and we all know people dont like games to push thier uber hardware
Im not saying the game doesnt need a few patches etc, but IMO, its a very good if slightly buggy game, thats demanding on machines because of some of the levels of detail in the way the lighting works in the game, and think it may well still look pretty good in a year or two, when more people's computers have caught up with the more realistic requirements!
<PS MAKE SURE YOU GET THE 1.001 PATCH BEFORE STARTING PLAYING, OLD SAVES ARENT SUPPORTED, AND IT FIXES A LOT OF THE BUGS, AND SOME PERF ISSUES>
Some screenies (not too amazing due to jpeg compression, looks quite nice when actually moving! 1680x1050 res) I am running the 'high' graphics preset, slightly tweaked, not maximum etc ingame, with Dynamic Lighting Enabled:
