thats probably the best i could squeez in, its 840 before MIR, and you get a Processor you can OC to match an 8350 pretty easily, a Video Card that at stock let alone OC wont have a problem tearing through any game, and an SSD for you OS and Programs so your Pc is nice and snappy, if you want you can drop the SSD or if you dont have a lot of storage needs, drop the HDD and go for 128GB or higher SSD.
If you're budget is before rebates- http://pcpartpicker.com/p/yxE5
If budget is for after rebates- http://pcpartpicker.com/p/yxF5 ( well worth the extra $16.48 to get the TPC 812, which cools almost as well as the Corsair H100. If not overclocking, either get an optical drive or a CM Hyper 212 Evo)
Then you can OC the GPU to 1GHz or more easily with programs like MSI Afterburner. If you buy an aftermarket cooler, with the TPC 812, you can probably OC to 4.7GHz and above. With the CM 212, at least 4.0GHz, but it will probably go to 4.5GHz, maybe even above if you get a really good chip
If you can always go with the most powerful single card you can buy, itll save you on getting a bigger PSU, hassle, and if you want to corssfire in the future you can and it will hold for even longer than two 6950's would.
