Hey guys i ordered me a Asus GTX 960 4gb Turbo graphics card today. My current machine is a mac pro 1,1 and i'm already running yosemite with a geforce 8800gt. Ive upgraded the ram to 16 gig already and i downloaded the web driver for it. Is there anything else i need to do before installing the card. Should i upgrade to el Capitan or stay at Yosemite? Also What steps do i need to take to install Windows 10 on here. I bought a separate Hard drive to slide in for that. Thanks guys
