Sorry, i should have thought a bit more before posting.
So the budget is $1800 aud (Australian)
Dont require monitors, speakers, keyboard mouse etc, just the box.
Not familiar with overclocking, so no.
No plans on SLI or Crossfire unless old card becomes too old and I can get another one for cheaps, perhaps its better to get an SLI mobo?
I usually buy my stuff from a cheap wholesaler in Sydney, msy.com.au.
