we built a machine using an Elsa Quadro2MXR (dual-head) and it came with one VGA and one DVI output.
to use two analog monitors, we had to use the included DVI to VGA adapter.
I thought it was just me, but when I cranked up the refresh rate in Windoze2K, the monitor using the DVI adapter still seemed to have a slight flicker, no matter what reseolution I used.
maybe you're right.........
