Hi!, i'm new in this forum and I have a question. I have a macpro, and I use the computer for work, but I have windows with one game. This game (shooter) had a eax sound and I have a headphones with optical sistem, 5.1, dolby... and all this things. I would to knowm if the creative x-fi Fatal1ty Pro run in macpro, in mac Os and Windows. Really... I only need run in windows, but if run in mac Os... it'll be better. I saw this sound card and... ASUS Xonar D2/PM... can I install any card in my macpro???, will it run in windows???. Thanks and see you !
