[OpenSPIM] computer configuration

[Ulrik Günther]

Hey Thomas,


in addition to Michael’s remarks, I’d like to add that the graphics cards in your listing are quite dated, but anyway still expensive — I found them for around 1000EUR online.


If you plan on running things like Multiview Deconvolution (http://fiji.sc/Multi-View_Deconvolution) on the GPU, you’d probably be better off getting a more recent card, like a GeForce Titan X with 12 GB RAM, instead. That card also costs around 1000EUR.


The main difference (apart from the Titan X having a much more recent architecture) between the two is the double precision calculation speed: The consumer (read non-Quadro) cards are artificially capped at 1/8th of the single precision processing speed. For most image processing tasks however, double precision is not necessary, but more RAM on the GPU helps tremendously.


Hope that helped :)


cheers!


ulrik

Online, I also found the HP Z840 that can accomodate a tremendous amount of ram, any recommandation?
