Hi folks, I have the machine in my sig. Right now, I use the machine for video editing and various Adobe programs. Since I do use the Mac Pro for the occasional game on Windows 7 bootcamp at the moment I am ok with what I have. The existing Sapphire is not the best but not the worst to be in both IT worlds in only one machine. In a view months there are a number of games coming out that I can not skip for my life, such as the new Deus Ex and Fallout 4. Now here ist the question for two possible scenarios I am looking at: #1 Keep the existing Sapphire 7950 and add one more 7950 to use crossfire for the Windows game. It would cost me arround 250 to 300 Euros for that. Pro: No driver hassle in OS X since I would have two Mac versions, less invest compared to #2, auxiliary 450 PSU would be needed. Con: less GPU power then #2 or #2 Sell the existing Sapphire 7950 ME for 300 bucks and get a Nvidia 980 from MVC. Pro: Way better graphics all around. Con: Fiddly drivers, high shipping cost to Germany, higher cost, uncertain Nvidia Web driver situation, maybe more downtime for OS X .. I am not sure which route to go. Somehow I would love to pimp that baby with a second white 7950 Mac Edition. It would be less money and more pimping with that Aux PSU (+ I really love mods) The Questions is this, how big would be the difference between Two 7950 Crossfired to One Nvidia 980 in Windows ?? What do you think, which scenario would you choose?
