That's not entirely correct, electricity travels at speeds almost similar to that of light so it doesn't matter if the card is stuffed in the board or wired and placed on a table it's not as if you'll be using several kilometers of wire. Regarding the resistance offered by the wires, there are lots of new technology to compensate for that otherwise just use thicker wires.

I understand the point that you are trying to make, but the closer the Graphics card is to the motherboard, the higher the speeds you can run. What this means is that there are shorter track lengths, i.e. less distance for the electricity to travel, less resistance. Now you probably can run a graphics card as a separate unit outside your PC case, but you will not have the same performance.

Does Nova review anything other than Asus? Fanboys make the worst journos.

that graphic vendors would separate the cards from the motherboard and put them in an external table-top box - hooked via bus extender card+cable. We don't need those monstereous contraptions, with their power requirement and heat generation, inside our case.
