Yuki, A couple of final questions...
Once you've bought the active DVI to DisplayPort converter (about $100), does this solution actually work out better cost wise than just buying two Nvidia boards (say a Quadro FX 380 or 580)? If so, what is better...? The added value of the desktop manager etc...? The fact that it leaves more PCI slots free...? Running cost...? I guess everything else being equal running one video card instead of two is better for long term running costs...? Finally... any recommendations monitor wise... I'm about to buy 3 x 24 inch.
