Two ATI Radeon X1900 XT in my Mac Pro?

Hello,

I need two ATI Radeon X1900 XT in my Mac Pro.

I have one and want to install another.

Has anybody done this?

I am informed that I need to connect power from the power supply to the ATI Radeon X1900 XT.

Is the connector already there? Do I need an internal cable?

Any ideas,

Thanks,

Dean

Mac Pro, Mac OS X (10.4.10)

Put the cards in slots 1 and 2 and set the bus to x8 x8 x1 x8. There are two power connectors, and each card should come with a power cable. There are reports that two cards will work with OSX, but Vista complains.

The DVI to Video Adapter will give composite video

Only one Video adapter per card (port 2). See Table 2
