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.

four cards no 

three cards  yes

to do four  you would need careful undervolt via msi afterburner

Reason that you cant?

Yes you can, in fact, you can do 6 cards as well, but there is not enough cables for most of 750w psu to do that.

I have 5 x 580 connected to my evga 750 and it runs stable.

Best thing to do, get yourself a Kill a Watt, Home Depot carries them, Amazon as well https://www.amazon.com/P3-P4400-Electricity-Usage-Monitor/dp/B00009MDBU

Measure how much your usage increases when you add a card while mining!

Understand your power supply efficiency and then decide if you have room left to add another.
Good read bout efficiency:
