Ok, it seems neither game will work with that card.
Medal of Honor: allied Assault requires:

Nvidia GeForce 3 or Higher
o
The MX series of Nvidia video cards are not supported
*
ATI Radeon 8500 or Higher

F.E.A.R Requires:
64 MB GeForceā?¢ 4 Ti or RadeonĀ® 9000 video card

At least those are the video card requirements. You may get by any error messages that come up, but the game won't run for shit. Sorry dude. you may be SOL.
