You don't need the Quadro if you're not going to use QuadBuffered Stereo
(Shutter Glasses 3D). In CUDA performance, the gaming cards are supposed to
run fine, sometimes faster than the more expensive Tesla and Quadro, that
are made to be more reliable and long living and have ECC memory, whereas
the gaming cards point on performance. This GTX looks very expensive, the
non mobile series is only half the price, if you do not really need a
laptop, I would think about buying a tower, just for the feature of being
able to upgrade the card in the future.

Betreff: vmd-l: Do I need a "professional" graphics card?

 

Friends,

 

I'm in the market for a new computer, and I'm pretty much sold on a Eurocom
Panther laptop. I am looking at the GPU options, and I'd like to get your
opinions on whether I should go:

4GB Quadro K5000M, 1344 CUDA ($1405)

or

SLI; 8GB; 2x4GB GTX 780M, 1536 CUDA ($890)

 

The internet seems to think that the high-end cards are only worth the cost
with CAD and 'professional' applications, but not for gaming. I'm not sure
where VMD falls in the spectrum of 'professionality' of its GPU usage.

 

Also, for quick NAMD+CUDA runs, I presume the latter option would be better,
but I don't have any better argument than "1536 > 1344".

 

Can anyone share their experience in this regard?

 

Cheers,

Charles McAnany,
