Build I've just done, which should be close to your needs. PSU allows for adding a 2nd graphics card. Have left out hard drive and optical drive, that you already have (trust they are suitable). Put in an SSD, but you can obviously drop that, if you don't want it.

PS
If you have local Microcentre, I understand they have $50 off deal on motherboard, with that processor (don't know how long for)

Should I wait until Black Friday to buy?

Malbluff, what you say seems to be the best option. However, I would like to hear a few extra opinions.
