How bandwidth intensive is Photoscan? Bitcoin miners aren't very bandwidth intensive for example, you can plug a graphics card in a PCI 1x slot and the performance would be similar to a card in a PCI 16x slot (because the card spends most it's time crunching numbers, and doesn't send/receive much data).
Is this the same with Photoscan? Could I use an extra graphics card in a PCI 1x slot, or would this card have low performance?
