Seeing double, twice, with Matrox M-Series QuadHead GPU

Matrox has announced what it claims to be the first true QuadHead GPU, the Matrox M-Series. Which begs the question, just how many monitors do you need? With 512 MB of memory, native PCIe x16 performance and a fanless design for quiet operation you might think Matrox has done enough with the new M-Series graphics card family. But you would be wrong. These babies are capable of stretching desktop applications across not two, but no less than four monitors.
