I took delivery of my new Mac Pro on Saturday and of course had to load up WoW as a benchmark! All I can say is WOW! My system is 2.66Ghz, 2Gb Ram, x1900xt graphics WoW is set to 50% Terrain Distance, all other sliders maxed, Full Screen Glow off, Vertical Sync off Framerates in Orgrimmar on Sun at 1630 GMT i.e. lots of people running around, averaged 50-60; MC run 45-60; On a Windrider 110! Of course this is before the OpenGL improvements as promised by Blizzard have been implemented. When they arrive, this baby is going to fly!
