Hi all,

I would like to create my first mining rig and, after I found so many ppl having issues with more than 3 cards, i would like to ask for some help:

Planned hardware:
Graphic card: 3x SAPPHIRE R9 280X 3GB GDDR5, when everything works fine, a 4th
Motherboard: ASRock 970 Extreme4 (but it has only 3x PCI slots, so which board can handle 4 cards?)


Questions:
1) I plan to run this via WLAN, using Teamviewer. Do you see any issues with that?
2) What motherboard should I use?  I didn't find one with 4x PCIe slots.
3) The card's spec are different on several sites, ranging from 250 to 750 Watts?
4) What power unit should I use, depending on the outcome above (3 or 4 cards)?
5) Can Windows 7 handle 4 graphic cards?
6) When running Windows 7, do I need to have dummy plugs for the cards?

Any help is appreciated, thanks for your time!
