For GROMACS itself there is no real special needs in terms of the graphics 
card.  Where that becomes important is when you are using a visualisation 
program to then view the trajectory.  So the best idea is to talk to the 
suppliers/writers of the visualisation software that you are going to use 
to find out the best option.

Personally I use VMD and have a workstation on its way with a ATI FireGL X1 
256M.  If you use VMD, check their emailing list, several discussions have 
occurred on the types of graphics cards to use.

Scaling with the current version of GROMACS between computers is not the 
best, even when high speed networks are used.  So to be the most efficient 
a multi CPU motherboard is the way to go.

Hope that helps.
