$700 computer build, australia

I plan on making a computer based on the $650 rig featured here

this is a few months old so is there anything I should upgrade on the list?
also, where would be the best place to buy parts that ships to australia? 

if someone on here can tell me a online site to get parts in australia, I'll build a badass PC list for you

this seems to be the best place, hopefully you can work with that 

CPU i3 3220

Mobo asus z77

Ram G.skill 2x4GB 1600

GPU 7850

HDD 1TB

Case thematake commander

PSU CM 550w 80+

idk on shipping

Thanks man I really appreciate it
I just have to ask if theres a reasonable quadcore cpu the I could use instead?
I might be doing video and music editing and from what I understand a quad core cpu may be beneficial

 

yeah but you'll either have to up your budget or comprimise on some parts like the GPU, either I can do for you tomorrow, as I'm tired and done 15 builds today, fun though

Pretty sure I've got a case sitting around anyway, maybe the money from that should make up for it.
 

i5 3330 would be a good quad

according to that it nearly doubles rendering capabilities, not so much for games but they get a boost if they use more than 2 cores
