Hi, I'm new to the Mac World. What Video Cards do I need to (if it is possible) to run three 20" Monitors? Will the virtual desktop spread across all three? If I get an 2.3 or Quad Core 2.5 with the 6660 Card which supports two(128 Meg Ram each) do I just have to get a 6600 to run the other one? Can you order this from Apple? I don't like the thought of having a horizontal line right in front of my face by only having 2 montiors, and the three 20's give me 5,040 pixels across instead of 2,560(30" Monitor) for the same price(I know they are not as many pixels high). I prefer Horizontal width to Vertical height and this setup gives me 5,292,000 of Pixels versus 4,090,000. Any thoughts. Thank you.
