am i right in thinking that if i want a triple eyefinity display with 3 IIYAMA PROLITE E2210HDS 22" WIDESCREEN LCD MONITORS i need to get a DPtoVGA converter. I have two ATi Radeon HD 5670 1GB cards installed in CrossfireX. A powercolor and a Sapphire. The sapphire has 3 outputs consisting of 1x Display Port, 1x HDMI, 1x DVI. and the powercolor has 3 outputs consisting of 1x VGA, 1x HDMI, 1x DVI. Which one should i use and what do i need?
