I’m a newbie with CUDA, so have several questions.
I’m planning to build quite a robust ray tracing system with CUDA. So my first thing to do is to select
graphics cards. :rolleyes:
It seems to me that Quadro Plex products are far more expensive than Geforce serieses, while their
computation power difference (in terms of flops) is not to big. (e.g., GTX 280(295) vs Quadro Plex D2).
So my first question is whether I should buy Quadro or Geforce.
If I use two GTX 280 cards and interconnect them using SLI, then can CUDA use them as if they were a single
device? If so, does it mean total 2GB memory availability? (GTX 280 has 1GB of memory)
finally, in a system with a arbtrary non-CUDA graphics card (ATI or old nVidia) and a CUDA-ready card,
can I use CUDA for computation and display for another arbitrary card? I’ve seen several postings on this issue,
but quite confusing. (Maybe, the answer is “it depends”? )
Many thanks in advance.
