I am an absolute CUDA beginner, in fact I lack the necessary board at this point. I have windows vista/ubuntu 9.04 (both 64 bit) and only a single pciex16 slot with no alternative monitor out. I have several very newbie questions:
Does the actual board the nvidia chip is mounted on make any difference when running cuda stuff, i.e. there are a variety of boards by different manufacturers (PNY, sparkle, evga, msi …) does the board on which the chip sits make any difference or does it just run procedures off the nvidia chip for image processing and will be effectively invisible to someone using cuda (unless it is driving a monitor, in which case I am guessing different boards may be more or less “hogs” with regard to nvidia chip resources).
Is it possible in vista or ubuntu (obivously running headless and logging in remotely) to make a single nvidia card available for cuda computation, but not for drawing to the monitor, so it is a dedicated card.
It appears that the geforce gtx 285 is a good computational choice (somewhat cheaper than the 295), but for a newbie it is hard to tell how big the tradeoffs are and I don’t think the guy at best buy is going to know. :) Is the 295 effectively like having two 285s (minus a bit) that are unrelated? I am assuming they don’t even share global memory since memory bandwidth is listed as 448 bit per gpu(?).
