I already have a Corsair tx650 watt power surply, This will see me through until i can upgrade my HD4870 gfx card.
So i finally decided on :-
CPU. AMD Phenom II x4 965 BE (the 955 is only $10 cheeper and a few FPS slower in Benchmark tests. I did consider it but thought $10 is worth a few FPS).
NZ$ 253.13
Mobo. Asus M4A79T- Deluxe. (Kept with this.... I like the idea of 4 pci-e slots for when i can afford to put 4 gfx cards into it. Hey i can dream. right?

).
NZ$ 358.47
RAM. Kingston Hyper X. 4gb - 2 x 2gb @1600mhz DDR3.
NZ$ 316.49
Op system. Windows 7 Ultimate 64bit OEM
NZ$ 334.53
Case. Coolermaster CM690 II
NZ$ 200.00
And if i can hide it from the wife, Samsung 21.5" P2250 wide LED
NZ$ 362.25 (Ideas with how i can sneak it into the house without her noticing would be helpful.

)
Total = NZ$ 1824.87
Shhhh, my budget is surposed to be $1500.
And yes we Kiwi's pay way more for hardware and software than other counties.
