[Paraview] Decent video card for ParaView on AMD Phenom board?

[Kārlis Repsons]

Hello in list!
Building a new workstation I got confused about video card. 
What would be a decent video card for Phenom or Intel quad board, that is used 
for hydrodynamics, deformation and free surface visualization? I didn't 
provide much of information, but there should be some sane choices for 
Phenom's computing power (that is - results it can produce for visualization 
in reasonable amount of time). And yes, supported by ParaView as much as 
possible / necessary. 
Your answer appreciated...
