Two motherboards?

[fishy]

Is it possible to hook up a set of two motherboards so I can run more GPUs?
"Linking" the motherboards?  Or will I have to run a big 8-slot MOBO rather than two 4-slots?

Run two motherboards.  Honestly i dont think you want 8 cards right together, sounds like a lot of heat and pains compared to two rigs.

Yeah, I believe the closest thing to what you're talking about would be linking them over a network and creating a cluster of sorts... but no real way to connect them in parallel and have it operate as one computer.

What do you think is the most gpus I can run without the mobo and other components exploding, catching fire, etc.?

 Why would you rather have two mobo's linked together instead of having two separate systems ? I  might suggesting looking into PCIE backplanes instead for what I reckon you are trying to accomplish.

There is no definitive number. AndrewBUD's motherboard fried from high power draw with only 4 GPU's. It all depends on your setup, with the right setup you could run 802 GPU's or more.

Wow.  802!

I was always surprised to see that those pcie backpane things arent used more.  I do realize however that theyre pretty expensive.

There is no standard for linking mobos, but some high end servers allow it. That being said, it's proprietary, undocumented, and obscure. Unfortunately, there is no good way to link mobos. Your best bet is getting two 16GB flash drives, and using that to host the OS, so you don't have to have two HDD's weighing you down.
