Many of the graphics hardware solution have inbuilt limits, e.g.  
textures can not exceed 2k by 2k in x and y and may be even more  
limited in 3D. Terarecon Volumpro is limited to 512x512x512 and four  
channels! This is independent of the actual size of texutre and/or  
video memory. What size (dimensions) does your data-set have? How  
many channels does it have? Is it a time series?
All this matters. The Terarecon card uses the PCI bus and is an order  
of magnitude slower to upload textures than cheap gaming cards. This  
is a disadvantage for large 4D data.
Can you give a bit more information about the applications /  
dimension of your data?

Thanks, Kolja
