Mac Pro Quad 4 Screens

[MilesTone]

I have a Mac Pro Quad core (early2009) with 1 gt120
As i understand it that there isnt a way to get 4 separate projectors (non-mirrored) with just this setup and a cheap DVI to 2 VGA splitter.
If i have 2 gt120s will i be able to run a 4 screen setup?
If so whats the cheapest way to get this setup to work?
Thanks
Miles

Two GT120s will be able to drive up to four displays (2xDVI and 2xmDP). eBay is the best source for GT120s at the moment, they go for around 100 bucks.
