Computer build compatibility and quality check

[Guest]

I am building my first computer, and have made my parts selection. I'm not really sure if what I've found is compatible or recommended so i came here.
I have a budget of (AU)$1600 with these parts coming just about that.
The computer will be used for gaming, watching videos, some everyday use, and some amateur 3D modeling:

Motherboard
Gigabyte GA-z77x-UD5H

CPU/Processor
I5-3570

GPU/Graphics card
AMD Radion Sapphire 7950

Hard Drive
Seagate SATA3 2TB

Solid State Drive
Sandisk SSD Extreme 120g

PSU/Power Supply
Corsair TX750

RAM/Memory
32g 1600(8Gx4) Ripjaws-z

Case
NZXT PHANTOM USB 3.0 WHITE

Haswell has just been released, so you may want to consider waiting for the 4670k and a z87 mobo, and perhaps the next generation of gpus as well.

What is the difference between a 3570 and a 4670. And how long would you anticipate my wait to be?
