Here is a link to all the parts I have thought of. (I like the NZXT phantom, but if there's any part more worthwhile that will get me better fps, go right ahead and tell me to get a cheap ass case)
I'm from Australia, and the site I use to buy computer stuff is pccasegear.com.

I generally picked stuff based on their reviews. Thanks in advance, awesome people of Tek Syndicate.
I'd recomend upgrading the CPU to a 3570K so you can overclock better, which you should be able to do pretty well with the 212. As for a GPU you should look at a 7870 (if you haven't already), it's similarly priced and offers better performance on many occasions (but not all). This is a comparison bench for reference http://www.anandtech.com/bench/Product/548?vs=660
Also may want to look at a radeon 7950 since it comes with an extra 2 games that you can either sell off to reduce your overall cost or keep to play. Either way you end up with a much faster card.
Pick the ram that has the lower voltage, if they are both the same then it doesn't matter much, either are good.
One more thing. I changed the motherboard because the reviews were good, it looks better and lots of people have had experience with it. However, it seems to have more bits sticking out around the CPU socket, and I was wondering if that would interfere with the CPU cooler. Would it touch the motherboard?
Do you think any of them would ship to Aus? I know some things on Amazon are available in US and Aus. Except freakin mousepads... Waited 4 months after ordering one for them to tell me it can't be sent to Australia...
