Hi there,

the big Bitcoin wave just hit Germany so I want to try this with two rigs mining me some money. But I have some concerns and I am not 100% sure about these things:

• Monitor dummy plugs:
    I want to run my two rigs with 4x 5850 cards each without any external I/O. Do I NEED at least one monitor to keep them running?
    Or do I just need one monitor to boot up?
    Or do I even need 8 dummy plugs for each card? Can those be bought or must they be built by myself?
• Two rigs, one account? How do I mine with two rigs to the same wallet file? Or won't it matter if I just have two wallets and simply split everything?
• Graphic card compatibility: Are there any graphic cards that won't fit on the MSI GD70 boards - like physically not fitting next to each other because they are too high?
    Can I mix up cards from different labels, like 2 Sapphire, 1 Asus and one XFX?
