is gtx 670 can handle bf4 at ultra

Solution
Your CPU and RAM are fine to run BF4, a very CPU intensive game optimized for multi cores, on Ultra.
Your GPU is fairly powerful and I'd say it can run 40+ FPS on Ultra and a much better 60+ FPS on High.
You may try Ultra, but it'd not be a wonderful experience, but high settings would be just right to play it with a solid 60+ FPS.
