$942, pretty much near the top end of your budget.
You could change a few things to get the price down.
I've included two seperate hard drives - one for the OS and apps. and the other to use as a video streaming drive when editing. I went for the i7 920 since Newegg still stock them to save a few cents. The RAM is ok to start of with but if your projects get large then you might want to upgrade later by adding another 3GB.
