GPU mining zcash/ether -> altcoin


I have some gear laying around and been reading up on mining and thinking of trying it out.

I have:

AsRock Q170M vPro Seasonic 1200W Platinum PSU Asus Radeon RX 460 4GB Strix Powercolor r9 280x 3GB

Laying around (prob some RAM aswell), but the Q170M supports 4 GPUs and mixing manufactures are not good from my understanding.

Was thinking

Computer 1

Motherboard: Q170M PSU: cheapest 1151 socket GPU: EVGA GeForce GTX1070 SC ACX 3.0 (3 of them) Ram: 8GB cheapest 120gb SSD 3x Pci-e Risers x16 Os: windows 10

Computer 2:

Motherboard: 3 supported one (dont know what) Psu: 850w platinum Gpu1: Asus Radeon RX 460 4GB Strix Gpu2: amd Radeon R9 280x 3GB GDDR Gpu3: amd radeon R9 290 4GB Ram: 4gb Hdd: 120gb ssd Cpu: what fits the motherboard. Os: ethOs

With 3x risers.

I have basically free electricity, place to have them without bothering somebody.

Will the setup for both computers work?
