Will this monitor setup work?

Hi,
I currently have a 24 ACD and I'm about to purchase another 24 ACD along with the 30 ACD.

I currently have the 4870 in my mac pro and I'm going to add the GT 120.

I will connect both the 24 LEDs to the 2 mini displayports on each card, and will I need any extra cables or adaptors to connect the 30 ACD to the DVI port on the 4870? I just want to make sure i have everything before the monitors arrive.

I'm buying those today from cpustuff.com since monoprice hasn't released thiers yet and who knows how long they will take.
