My guess is that you can use as high a resolution sensor as you can afford!
Parallella is pretty much akin to a ZedBoard plus Epiphany chip, and in fact the prototypes were precisely this: a ZedBoard with an Epiphany FMC module. The only thing you might want to check is how much GPIO the Parallella Embedded has vs. ZedBoard, so that you can be sure you will have sufficient for whatever sensor you plan to interface.
