New Gaming PC - Are all these parts compatible?

[dylanm]

I am planning to build my own custom gaming computer...

After days of research, this is what I've come up with.. Can someone please take the time to read through this list and tell me if all the parts work properly with each other?
(BTW if i were to change my selection of RAM to this:

http://cgi.ebay.com.au/OCZ-OBSIDIAN-DDR3-1...#ht_4431wt_1094

and my selection of a processor to an AMD X6 1055t, what difference would it make to the overall performance of the system and does the motherboard support it?)

Also. Is there anything you would change about this system to make it better without adding more than a few dollars to it?

PS. I live in Australia, and Newegg doesnt deliver here. Also, most American sites, while usually having cheaper prices, charge huge amounts of money for shipping.

Do you plan on getting another GPU in future? If not, you don't need anything more than a 500W power supply - should save you some money.

What games do you plan on playing? At what graphics level do you want to play at? What resolution are you playing at? Depending on the answers to these, you might want to go for a better GPU.
