WRONG Just wanted to let you know that this quote is completely incorrect. I have a brand new G5 with a 6800 Ultra running dual 30" inch monitors and it definitely does not take 2 GPU's to run. What it needed was the Dual Link DVI. This is essentially sending 2 completly different DVI signals through the same DVI Cable. They accomplish this by utilizing the unused 12 pins (wires) that currently run through a regular DVI Cable. Basically, the GPU can definitely handle driving the amount of pixels, what it cannot do is output the 2 separate signals. This dakes another specialized dual TMDS driver chip to accomplish. Anyway, just wanted to output the information.
