how to determine which video card mac 3,1 is using

[skiguy]

Hi Everyone,

I have a Mac 3,1 into which I just put in a gtx 660. It also has the x2600.

When I boot up plugged in using the gtx 660 (there's no screen until I login), it shows the gtx660 card.

When I boot up plugged into the x2600 I see the bootup and it shows the x2600 card.

However, what if I have one monitor in one card and one monitor in the other? The mac still shows the x2600 but if I play a game which card will it use?

Thanks!

Should be the card that attach to the monitor, but I am not 100% sure about this.
