I'm going to be upgrading my system soon - and need to start thinking about components. I'm an ATI kinda guy, but I have to say - that ATI drivers suck. Not for 3D gaming - because those rock - but for the desktop they are no good for dualhead users.
You can't enable the taskbar to span across the bottom of both monitors.
So - do the Catalyst 4.7 allow it?
If not, I'm going to buy an nVidia card and use 44.03 (yes ancient!) because those drivers are the only ones (apparently - after installing EIGHT different nVidia drivers) which allow taskbar across both screens - without major screwups.
