Heavily Customised PC $2000

I want to build this computer for daily use and it will see some heavy gaming during the weekends. BF4, Payday 2, WOT, War Thunder, Medal of Honour, Far Cry 3/4(when it comes out), Watch Dogs (Comes with the GTX 770), GTA IV, GTA V (when Released)

Also, I currently have a GTX 630 sitting at home doing nothing... could i use it for dedicated PhysX ?

HDD (I currently own these)
160GB @7.2k 2.5"
250GB @5.4k 2.5"
320GB @7.2K 2.5"
320GB @7.2k 3.5"
