I am building a Hackintosh this upcoming Christmas and I have a budget of 1100$. My build is Intel core i7 4930k, a Gigabyte Gax79 motherboard, 16gb Crucial Ballstix Sport Ram, EVGA 600b Power Supply, 2 wd blue 1tb, 2 64gb ssd. I plan on adding a r9 270x later on and after that a geforce gtx 780. Will It Affect compatibility?
Yes, it will. Check out the list of compatible devices on http://www.tonymacx86.com/wiki/index.php/Graphics_Card_Database
