Okay, so I am in a big rush to get this PC finished, I am in Aus and my local shop is having a sale on just the Galaxy GTX 670, but there is also the Gigabyte 3gb 7950 OC. Right now, they are both the exact same price, they said that they have never heard of galaxy and it would be safer to go with the 7950, they also said that the 7950 will have better performance, I didn't want to just take their opinions, I want your amazing opinions too! I hope you guys can help :3

So this is the first one, just look for power supply on the left
pccasegear.com.au
This is another shop that is down the road from my house, just look for case a power supply on the left
umart.com.au
And this is a shop that my dad works next to
msy.com.au

if you are going to OC, the 7950 will probably give you as good or better performance.

But what if I OC the 670... It will be better than the 7950

Yes it will be, GTX 670 is already better than 7950 at stock speeds. It would even be better when overclocked.
check out the overclocked max clock speeds and max memory clock speeds an OCed GTX 670 can do compared to an OCed 7950 and other cards as well.

note: GTX 670 was deemed to be so good, it blew off the suppose-to-be-better GTX 680 in terms of recommendations.
quoted from http://www.tomshardware.com/reviews/geforce-gtx-670-review,3200-17.html

"We have every reason to recommend buying a GeForce GTX 670—even as an alternative to the GeForce GTX 680, which is marginally faster, but 25% more expensive."

about your ram:

is that is?

Asrock z77 extreme 4 is listed in one of the qualified motherboards list so you don't need to worry.
