Hi Nick,
We are planning to buy a GTX 460 1G card because of the cuda support of Freesurfer. It seems the most reasonable buy for CUDA device, 336 Core, 1350MHZ shader, and around 100 $ cheaper than the 285GTX. Does this card has double precision support? And what is you guess (time) about the stable CUDA support for let's say 50-70% of freesurfer stream?
Thanx,
Gergo

we're still trying to find the 'lowest common denominator' card to support, as clearly have more memory and double precision support allows more efficiency options in development. currently we target the Quadro FX4800, which is about the same as the GTX 285, as the LCD card, but we test and develop on a C1060 and C2050 as well. a tesla card is useful if you plan to process multiple subjects on one processor (assuming you have a multicpu with tons of memory) and you want to have a gpu per processor. otherwise, for our current gpu stream, a tesla is overkill.

Hi Nick (and others),
do you already have positive experience with ATI cards, too? We think
about
buying a new workstation with lots of GPU power so it would be great help
to
know what really pays off: GeForce GTX 480 or ATI Radeon HD 5870? Or
should
we go for Nvidia Tesla? What kind of tech specs are important here?
Double
or single precision floating point performance, number of cores, amount
of
memory...
Thanks and cheers, Georg
