The motherboard you got should be fine.
The delux is more expensive, primarily because It can handle a ridiculous 4 card gaming rig.
On the SSD's, no matter. I suggest you just install them like two sata hard drives. Use one for the OS and some apps, and the second for whatever else you might want fast access to. Use a large hard drive for any overflow and backups.
When you load windows, set the sata mode in the bios to AHCI, not raid or IDE.
I like EVGA as a graphics card vendor. Something like a GTX 550ti should be good.

EVGA has a 90 day trade-up program if you register, and want to trade up for a stronger card later.
The stronger cards let you increase the detail and eye candy, as well as increasing the normal frames per sedond you see for smooth gameplay.
Games will be played on your primary monitor, so attach that to your discrete graphics card.
Some games can span multiple monitors, but I think that is unusual. Out of a dozen games I have, none will do that.
Unless you are thinking of a particular game, expect that all games are one monitor games.
The integrated graphics is perhaps the power of a $50 discrete graphics card. That is plenty for HD movies and the like.
Even though there are three ports on the motherboard, you can only use two at a time.
It is no problem to attach your fourth monitor to the second port on the discrete card.
Windows will let you use all of these as an extended desktop. You can drag the windows around as you wish.
You will want an adequate psu. Here is a list of the psu's you will need for different cards:
GTX550ti needs 400w with 24a on the 12v rails plus one 6-pin PCI-E power lead.
GTX560 needs 450w with 24a on the 12v rails plus two 6-pin PCI-E power leads.
GTX560Ti needs 500w with 30a on the 12v rails plus two 6-pin PCI-E power leads.
GTX570 needs 550w with 38a on the 12v rails plus two 6-pin PCI-E power leads.
GTX580 needs 600w with 42a on the 12v rails plus one 6-pin and one 8-pin PCI-E power lead.
GTX590 needs 700w with 50a on the 12v rails plus two 8-pin PCI-E power leads or 4 6-pin power leads.
My short list of quality cards would include Seasonic, PC Power & cooling, Corsair, XFX, and Antec.
It is not wrong to overprovision the psu a bit.
I also suggest you get a modest aftermarket cpu cooler.
The stock intel cooler is notoriously difficult to mount properly.
A cooler with a backplate mount is easier to install, and a 120mm fan will keep the pc cooler and quieter.
Look at the cm hyper212 or Xigmatek gaia which should cost about $30.
---good luck---
