First off all, Hi! I'm new to these forums so I am a complete noob. I already built 1 hackintosh before and it is still working, and I have 2 macbooks. So I currently have a computer that I built 2 years ago. I've done my research, and I think all the parts are compatible. My question is, can you have 3 monitors on Mountain Lion using my graphics card? My graphics card is the Sapphire Radeon HD 6850. I have 2 monitors hooked up on 2 DVI ports, and 1 more monitor hooked up with an active display port adapter to the display port. Will this work in Mountain Lion? I've never installed Mountain Lion on this computer yet by the way. Also, is there anything I need to do to make it work? If you guys wouldn't mind answering (You don't have to), will this build work on mountain lion? I already checked but double checking just in case. CPU: Intel i3-530 GPU: Sapphire Radeon HD 6850 Memory: 8GB RAM Ask me for other specs, too lazy to put the others.
