4870 dual screen

[LCS/drummer]

I know apple says you need two GT 120's for a dual screen, but couldn't you have a MDP for the first screen, then get a DVI to MDP adapter for the second screen? or would OSX not recognize it?

I've just been reviewing this. I ordered the 8x2.26 with the 4870. I've already got a 20" ACD (w/DVI) and a ViewSonic N1630w which can connect via RGB or HDMI. I am planning to connect the ACD via DVI and the ViewSonic via MDP->HDMI adapter.

The ATI product page says:

Two independent display controllers
Drive two displays simultaneously with independent resolutions, refresh rates, color controls and video overlays for each display
​

So you can run 2 displays (within spec) and it, I assume, doesn't matter which port is primary.

Can someone with a 4870 shipped in the 2009 MP confirm these options?

There are two ports per card. Thus, two monitors per card. Apple does NOT say that you need two cards for two monitors.

Perhaps in a week or two...they are all very busy running benchmarks right now.

What's so hard about looking at a picture of the card? There are two ports. That means two displays.

Seriously.
