Well, if your buying over time... I'd say start w/ a new board and proc. Get a s939 board and an opty 165 or x2 3800. Then I'd say, if your willing, get one of the G6150 mobo's with the onboard GFX.. they'll cost you about $90 and you have enough money to have a working comp atm. Then you can get a good GFX card when you have the money (you'll also be able to wait a little while till DX10 cards come out. then upgrade the rest of the parts (starting w/ a new HD or ram is what I'd suggest) when you get the money.
The upside is you'll have a working DC computer right off the bat.
You'll also be ready for a pcie GFX card when you get the money, instead of buying an outdated mobo w/ agp and being forced to buy a new mobo when you have the $$$ for the GFX card.
Downside is you'll be taking a step back graphics wise for a while. Tho the onboard G6100 performs about 2 times better than my Radeon 9200. It gets 20-40fps in Source games (On high, w/ full HDR) while running in 12x7. I'd imagine the G6150 would do a bit better.
It's really what you're willing to do and how long you want to wait for a working comp.
I don't know any AU sites, so I can't find product suggestions.
