Crazy pictures on this thread. Didn't even know what I was looking at with some of them. I have a question. I saw lots of pictures where people had multiple video cards just sitting outside or strapped to a board. Then I just saw the power connections on those cards but didn't see any data connections. How are these cards connected to the mainboard? How many video cards can a mainboard have? There are only 1 or 2 PCI-E slots usually on a mainboard, right? I have the ability to get some high end ATI cards. I also won't be paying for any electric, which makes it fairly good for me. I have a few mainboards not being used but find it difficult to know how to connect 4 GPU's to one mainboard, or even more if possible.
Thanks.
