Three display setup performance

[whatnot]

Hi,

I've browsed through old threads and found some experiences but nothing too recent of multidisplay setup and as the patches have done major work on the graphics so I think it's better to check the latest state of affairs.

So what I'd like to do is a three display setup either with NVidia or ATI products. I've seen

this guy

and

that guy

doing it but due to a costly investment would like to learn more.

So what kind of gear do you need these days to achieve that GPU and CPU wise with maxed out setting?

Both NVidia and ATI have solutions for it, but which one would you recommend and why? (I know ATI has still some gfx glitches)

Can I achieve it with one card?

Thanks a million in advance!
