1 complete lockup (During 1.02)
5 Year Old machine.
Core 2 Duo (Overclocked to 4GHz, but always has been)
8800GTX (Also Overclocked)
4GB RAM

Zero framerate problems (towns or anywhere else).
Zero new problems, as far as I can tell, caused by patches. (Other than that one lockup.. and we''ve all had 1.02 for quite a while)
