Windows xp and dual screen never really worked, if you attached 2 monitors to your pc you could hardly put to WoW windows up because on of the windows would be lagging and overall bad performing. The story was that vista was better at this, never tried it myself, and that you hardly had any lag using 1 gfx card and 2 monitors with WoW windows on both monitors.

My question was, if anybody has tried such a setup on the new Windows 7. I know its still beta release but I read such good things about it. So anybody using 1 pc, 1 gfx card on windows 7 with dual screen and good running wows on both?
