What is the "best" F1 racing sim on the market for the PC? To qualify "best", I suppose I should say that I prefer realistic physics modeling, good graphics, up-to-date track maps, good sound, and a very positive sense of car control.

I haven't been keeping an ear to the ground on the subject since EA Sports stopped updating their F1 series. I currently find F1 2002 to be highly realistic but I have a bit of a problem with occasional video lockup (which, now that I think about it, could be my system and not the software). I never bothered to pick up the follow on "Challenge" version, as it didn't seem to offer anything new.
The only experience I had leading up to F1 2002 was Eidos' Forumula One (which I thought was quite good at the time) and, prior to that, Microsoft's CART Precision Racing. CPR wasn't bad, IMO. The ovals drove me nuts but the road and street courses were pretty fun.
I do own an Xbox but I don't have a wheel and pedals. I'm loathe to go buy these items because:
- The ones at the store look small and cheap
- I'd feel like a dork buying one
- There's no place in my living room where I'd be comfortable mounting a wheel
- I have a nice, big, hi-res 21-inch monitor for my computer

Anyway, if anyone has any suggestions, I'd appreciate hearing from you. Otherwise I'll just have to enjoy the occasional rip around in the old (but not so trusty) F1 2002.
Oh, and a side question: any good driving sims out there for Linux? I was pretty impressed by the X-Plane demo I tried - easily a rival to Microsoft's Flight Simulator and has won many converts, I hear.
