AMBER will run on any NVIDIA GPU that supports Hardware Revision 1.3 or
later. I.e. hardware double precision. Not sure where the FX4000 fits on
this but I think it should probably work fine. We have had some issues with
reliability of GeForce cards but have never properly tested the quadro
cards, mainly because they cost so much that you could just get a GeForce
and a Tesla instead in most cases. So I think you should just try it and
report how it goes. Running the deviceQuery command from the CUDA SDK will
tell you the hardware revision.

All the best
