Heres my setup, but i cant get to work. any thoughts appreciated.

System config:
1. B250 Mining expert
2. Intel 3930 Celeron
3. 4GB RAM (4 more on order)
5. 60GB SSD
6. Linux OR Windows, i have access to both
7. 12 x AMD RX480 Sapphire, 8GB OC Edition (BIOS mod to 30m/s in windows)

What would be the best OS to use for this setup?
