driving and fps games are really great with multi monitors 5760 x 1080 wallpapers are kinda limited tho.

Depends. AMD's Eyefinity is good for more than two monitors on one card due to it using a DisplayPort connector that has it's own clock, something that nVidia still don't have. Not only that, each monitor in an Eyefinity setup is independent thus you can use monitors with varying size or resolutions and mix them up and it will still work.

Nvidia on the other hand could only support two monitors per card, and 3 if you are using SLi (nVision mode). The problem with nVision is that you can only use 3 exact same monitors, and they are configured as one large monitor instead of 3 separate ones, something that for me is an issue as I don't want one large space, I just want multiple workspaces.

for graphic work, it's due to popular graphic softwares like the ones from Adobe are optimised to use nVidia's CUDA technology. But unless you are doing a  very large graphic work or video editing involving a lot of HD vidz, the difference can't be detected in real life.

Sharing my setup at work..

Yes. I am doing just that actually. GTX570 SLi --> main gaming monitor/Adobe Premiere, HD5450 --> 3 other monitors

Not really, since the HD5450 is not a powerful/power hungry card.

if u want more monitors together with awesomeness, u need the ooomph from GCs and sacrifice more money into the bills lol
