It did work once (with Far Cry, amazingly well at the time too considering the age of the PC) but when I restarted the computer I never got it working again.
Might have been going off the point there, but switching from Nvidia to ATI is probably less straight forward than staying with one brand. Make sure you know all about the compatibility of your specs (I'm sure many members here could help).
I hope I raised some points to consider, cheers!
