Dead Rising
Burnout if you don't have it on another system
PGR 3 or Forza 2, both cheap but wouldn't bother buying both as they will consume too much of your time if you put the effort in also sequels might be out later this year. I picked them up for around £5 second hand.
Bioshock.

All very cheap now.

I second the recommendations for Dead Rising and Bioshock.  Excellent games both.
