The $139 dollar motherboard is legit, however, you can't buy it separately - it's a motherboard upgrade which needs to be bought as an upgrade to a new PC system from Mission PC.

That second motherboard is the GA-890FXA-UD5 which is meant for AMD CPUs.

Don't go for the GTX 275, it's old tech - go for the GTX 460 which is faster and supports DirectX 11, and has better efficiency.

I know your budget is $240 AUD, but I'd spend the extra $29 on this motherboard:

It's just that much better than the GA-P55-UD5.

oh and anutha thing PSU ? Dont get one with the case im pree sure thats the last thing i need ill post up the things ive got now ill send u the list here:
Thermaltake Armor + Black Steal Case - $244.00
Kingston 2x2GB DDR3 1333MHz Ram - $129.90
EVGA GTX 460 786MB - $290.00
Intel i5 750 - $240.00
Asus P7P55D E-PRO DDR3 Motherboard - $269.00

All i need is PSU and HDD? and possibly CD bay unless i can salvage from my computer atm

It's better for these reasons:

1. As mentioned, SATA III and USB 3.0.
2. The P55-UD5 is pretty much unavailable, it's discontinued.
3. The P7P55D-E Pro is cheaper.
4. It seems like some P55-UD5 boards have the Foxconn retention bracket which applied uneven pressure to the processor, causing it to be burnt, it may or may not apply to the board.

Any suggestions? HDD i want 1tb PSU no idea about voltage needed to run above specs and ODD i guess i could just figure out myself
