1ST PC I'm building and can use some help

I need help on building a PC. I need it to be powerful enough to handle CS6 and 3D modelling programs like ZBrush and 3ds max. I already have a case(Zalman Z11 Plus), a 60GB corsair force series 3 SSD ( for windows), and 8GB of Corsair Vengeance memory and this is what i was thinking of getting so far.

 

CPU : Intel i7 3770

GPU : EVGA GTX 670 FTW Editon

PSU: Corsair 600 watt

RAM: Another 8GB of Vengeance Memory 

Motherbord : IDK

Can someone please help me. Please and  Thank you.

And my budget is $1200 I'm trying not to go over that.
