While OSX has a host of issues (more than Windows or Linux) the machine itself is actually quite well spec'd for Dolphin, Anti-Ultimate. The OP can always dual-boot if necessary, but the hardware itself is pretty good in this case. At least on paper.
@AVCP333 - Which model i7 is it exactly? Also, which games are you planning to play? The GTX 780M should handle most games at 3x IR (which is actually larger than 1080p) with some AA (usually MSAA, though you might handle 4x SSAA in a number of games).
