Quad Crossfire vs. Quad SLI

If you've got a bunch of extra money laying around and you want to spend a bunch of it on a killer gaming system, you may want to consider multiple graphics cards.  Vortez has a comparison between some Quad SLI GTX680's and puts them up against some Quad CrossfireX HD7970 cards.  It's safe to say that if you're running a single monitor, you don't need this kind of graphics power.

How do they scale? What is the power consumption like? Are they noisy? Are they hot? And of course the question everyone wants to know - how do they compare. So for this review we will be looking closely at both cards and comparing 1v1, 2v2, 3v3 and 4v4 which will allow you to make the best choice dependent on your preference of multi GPU setup.
