$500 fully working budget Hackintosh build
Here is a great list I put together that has fully compatible parts for 10.12 Sierra, with graphics acceleration.
The full cost of the build is $510 USD, with $10 mail in rebate if you choose to do so.
Skylake CPUs are fully compatible in Sierra, so no need to worry
Simply follow the Sierra guide using MacPwn from https://www.hackintosh.computer, burn the USB, and boot with -v and nv_disable=1 and install!
Now simply download this file http://us.download.nvidia.com/Rqor80X9RrVcISR7dpCsIE5jO75hqagH/WebDriver-343.01.02b02.pkg
install and then open your EFI parition (finder > preferences > show hard disks> and navigate to "Clover" "config.plist" double click it, and it will open with Clover Configurator. Under boot, use -v nvda_drv=1 and darkwake=0 reboot. You should now have graphics acceleration working.
To get sound, use the All In One sound patcher from this site, and sound should be working on the motherboard.
Finally, for iMessage, Facetime, App Store, and iCloud, follow this guide here STEP BY STEP
You should now have a fully working, great system for video editing and gaming.
DISCLAIMER: I have not bought these parts myself, I simply know from experience they are compatible and will work great with OS X Yosemite
