Hi guys,

This is my first mining rig and I need some insight from you guys:
> 8x MSI GTX 1080ti Gaming X
> 8GB RAM
> Biostar TB-250 BTC Pro
> Intel G4400 Skylake Dual-Core
> 8x Molex risers
> WD Green 120GB SSD

To power this, I bought:
2x CoolerMaster V1200 Platinum Power Supply. Will the two V1200 do the job fine or should I get an additional small power supply to separately power up my motherboard and risers?

My electricity price is very less, so it is negligible. It would be great if you guys can help me overclock my card by sharing Afterburner configuration. I'm still confused with that part.

What should I mine to make more profit with my Nvidia cards? I've checked whattomine.com but the value keeps changing. Any stable and specific coin that Ican mine?

I would really appreciate your help. Thank you very much in advance.
