Guys: If i buy the new retina 5k iMac, can I run two apple external monitors at the 2560x1440 resolution? so i can have three monitors including the rImac 5k? Right now i have a late 2013 27 inch iMac connected to two external monitors running at 1920x1080. Im planning on buying two apple additional monitors and I want to know if the rImac can handle the load? Thank You All for your help.
