Motherboard for mining.

I'm looking for a motherboard to mine ETH.

Yep, i know Asrock h81 pro btc vs Asrock H97 anniversary, but they've stupid price on Amazon ( 179-190$ from seller ) LMAO.

Now, i'm using Gigabite z170x gaming 7. It's just detect 4 GPU -damm it-

I sent a message to Gigabyte support, looked around website. You know !! Z170 maybe support from 4~5 GPU depend on brand, it said some pcies control by chipset and some control by cpu.

So... I'm looking for a motherboard which can detect from 5-6 gpu.

Thank for reading. F*ck z170x chipset.

P/s: any ways to crack win10 ?? Or use ubuntu 16.04 ?? I'm using rx 480 mix with rx 470.

Sorry about my poor english.
