System Usage from Most to Least Important: Gaming is the priority.

Parts Not Required: keyboard, mouse, monitor, speakers, OS, may re-use HHD and DVD burner

Preferred Website(s) for Parts: mwave.com.au seems to bee the cheapest australian website i can find, but really any site that is suitable for australia is fine.

Country: Australia

Parts Preferences: never had an intel cpu or an SSD before, i would like both for this reason.

Overclocking: No

SLI or Crossfire: what is this?

-------------

i plan to run windows 7 64-bit.
going to re-use a 1T HHD, and a DVD burner.

the video card needs 500W, and the CPU needs 77W, so i guess i need a 600W PSU?
what are recomended brands?

i also haven't decided on the case, but i want it to be a smaller one, as my motherboard is a Micro ATX.

have i missed anything critical?
and, are my above choices compatible with one another?

More about need assistance build
  1. SLI/corssfire is the act of running two identical (or for AMD very similar) video cards in parallel to use their combined rendering powers for gaming etc.

    if you plan to add a second 7850 or 7870 later, got with susan's suggestion of a 600W power supply. otherwise a nice 450W or 500W will be more than sufficient
