Need help for a new build

[FrodoNorris]

Ok so I have a budget of $1300 I can't go over that, that is the max. Anyway I want to build a gaming pc for high end gaming I'd prefer to have a nvidia GPU in it and an intel CPU. If somebody could help that would be great I'd like to buy the parts from pc case gear because I live in Australia and it's easier for me to buy from them because of postage costs and thongs like that but anyway. I don't need a moniter keyboard or mouse but I do need an OS preferably windows 7.

Thanks in advance
