will my build run bf4 and other next gen games at 60 fps minimum?

Solution
The video card is going to be a weak link. Its ok, I have the 7870 heavily overclocked that puts it close to the 270x, and I can do BF4 around 40-50fps on ultra at 1080p when I played it. Mantle might boost that up, but newer games are going to demand more. I'd boost up the video if you can now to give yourself some more headroom for newer games. My 40-50 would dip sometimes too, so if you want a min 60fps all the time, on ultra, better shell out some more video card monies.

Drop the CPU to the 4690k and spend the 80 bucks or so that you save on more GPU... you will have a much nicer gaming rig overall. Try to find a Z97 board too, just in case for the future. If that's not possible then I would probably drop the 4770 to the 4690k anyway and get an SSD which will help make your machine feel nice and snappy and fast, even if it's just 64GB or so and use SRT as a cache to your spinning disk. While it won't help with actual in game performance, it makes other day to day use and loading times drop dramatically.
