Hello,

One crypto mining expert advices me to have the following configuration for best cost/effective machines. Could some experts/gurus comments on below config:

Item
1. Giga. B250-Fintech B250 LGA1151 D4 ATX  (1x)
2. 8GB D4-2400 C16 SRZ ADATA  (1x)
3. Intel G4560 3.5G 2C/4T 1151 CPU  (1x)
4. MSI RX580 Armor 8GOC D5 PCIE  (6x)
5. Giga. GTX1060WF20C 6GB OC D5 Windforce  (6x)
6 Gamemax 1650W 80+GD (Gold) ATX PS  (3x)
7. A-DATA SU650 240GB 2.5 SATA3 TLC SSD  (1x)
8. CDT PCI-E 1x To 16x Card W/USB3.0 cables  (12x)

Additional questions:
1. Does mixed graphics cards give greater performance?
2. Is GTX1060WF20C a better cost/effective option than 1070 or 1080?

Thanks for your comments in advance.
