Ohh, that's a roughly $650US build.
This one is I3 based with all the money in graphics. It does will. http://www.tomshardware.com/reviews/build-gaming-pc-overclock,3159.html
If you want a less gaming focused build, go with an i5-2300 or i5-2400 and see what's left for graphics from this list: http://www.tomshardware.com/reviews/gaming-graphics-card-review,3107.html
If you prefer AMD then wait a month for Trinity to come out and see if you like it. Otherwise there are no really good AMD plays unless you catch a really cheap bundle.
