Each block is stacked on top of the previous one. Adding another block to the top makes all lower blocks more difficult to remove: there is more "weight" above each block. A transaction in a block 6 blocks deep (6 confirmations) will be very difficult to remove.

On Win7, try re-installing the drivers for the 6990. I have to do this if I am overclocking and jack them up sometimes. Also, you will need to plug another monitor into the other card or switch the cable back and forth to trick WIndows.

Or there are the dummy plugs you can find with a forum search.
Time is money. This means that if you have spare time, you can use it to make money.

Modular, open, and stack-able miner case.

the miner can only use 1 GPU. you need to run a new miner on each GPU.
