Triple head setup

I'm about to build a new machine (Linux+XP) for which I need a triple head setup.

Quad video cards seem to be horrendously expensive, am I right that I should be able to use pretty much any motherboard with onboard video as head 1 and then add a dual-head card for heads 2/3 ?

I was looking at using Asus M2A-VM AMD 690G as the mobo and a PCI video card, would this work or would I need to go the AGP route ?

Thanks

Yeah that should work.

That motherboard doesn't have AGP, so you will need to go for PCI-e. You'll also need to get an ATI based card or the drivers between it and the onboard chipset will fight like cat and dog.

I am curerently running 3x 19" samsung monitors with the matrox triplehead2go, its a great solution i find and i can play quite a few games over all the monitors and all hl2 mods, you could also do SLI and disable sli for when you don't want to game and use all 4 outputs and when you do want to game just use the biggest screen and enable sli, or you could buy a pci card thats probably the cheapest solution
