I hope I don’t have this issue, I got a 320MB 8800 GTS as well and gonna switch to server 2008 later 🙁
except I won’t be using International Drivers, the latest USA English ones are 180.42 Beta’s
Call of Juarez works on mine, I didn’t get a script error during the install, I’m using Server 2008 Standard Edition (32 bit)
However I do sometimes get a crash error during the game startup, minor issue.
