Ok, Looking to replace an aged Mac Pro with a Macbook Pro (retina or non-retina doesnt really bother me). I've got 2 displays. One currently connects up through DVI, one through Display Port. They support both DVI and HDMI. Can the new Retina Book power 2 displays (e.g 1 via Thunderbolt (as display port) and one via the HDMI? Can the non-retina ones do the same?
