Hi Guys, I'm in Australia and i'm looking to build my first pc. Ive started with a Thermaltake case, and have a ThermalTake 550W Smart Power power supply on the way. I have approx $600 left in my budget on the box, and i would really like advice on picking some great midrange motherboard/cpu combos that i would be able to run 1 graphics card to start with, with the possibility of upgrading to a 2nd card in the future. All thoughts are greatly appreciated.
