I have the mac pro dual core, 2.66GHz. It has the ATI 1900XL. It's still running strong, however I've become addicted to more monitors and I'm planning on getting a second one however I've been screwed by the discontinuation of the 23" DVI version because that's what I have as a main monitor. So my choices are 20" or 30" now, or the new one with some adapter that isn't shipping. So I'd like to get a 30" I think, and put the 23" to the side instead. yes I know there are cheaper monitors but I'm looking for some commonality out there. However I also have a 19" LCD 1280x1024 I use for 'junk' (non-photography) things like iCal, mail, etc. To hook that + the 23 + the 30 up can that be done without investing in another video card?
