Building a gaming PC

Hey there,

I'm looking at building a gaming computer but would like to stick to a budget of about AU$1000

I play most of my games on a large 60" 1080p LED TV with 5.1 sound if that makes a difference. The DVD drive and maybe a few fans will be taken from previous computers.

With a bit of help I've made a list that looks something like this,

1) Western Digital Black 1TB SATA3

2) SilverStone 750W Power Supply

3) Gigabyte GA-Z77X-D3H MB, Intel Z77 Chipset, Socket 1155, 4x DDR3

4) Intel Core i5 3570 LGA1155 CPU 3.4Ghz 6Mb Cache Ivy Bridge

5) Corsair Carbide 300R Black Mid-Tower Gaming Case with Side Window,

6) MSI N660TF2GD5OC GTX660 2GB HDMI DVI

7) Corsair 8GB (2x4GB) DDR3 1600MHz Dimm, Unbuffered, 9-9-9-24, Vengeance Pro Blue He

This comes to around AU$1044

Any suggestions, feedback or advice would be gladly appreciated.
