Brian,    

I'm getting ready to test a brand-spanking-new ATI Radeon 8500.
Since I'm currently using a Matrox G400 MAX, it sets a pretty   
high benchmark I think. I'm using Win2K SP2, a 21" primary
display (1600 x 1200) and a 17" secondary display (1280 x 1024).

I've heard very good things about the  dual display output of the 
Radeon 8500. I'm hopeful that the  drivers play nicely in Win2K 
with all my CAD applications,  including Protel. I'm anxious to 
see how the ATI/Appian Hydravision dual head control software 
works. The demos I've seen look very nice, but... if not, I'll 
just stick with the G400.
