I had a similar problem..
Windows 7 64-bit
i7-2600k @ 3.4GHz
GTX 770
16 GB RAM
Running 331.65 drivers. (latest beta).
To be fair though I only had it once. All the other times my whole computer freezes up after a few minutes of gameplay.
I'm running BF4 smoothly on ultra settings and have no issue with framerate or lag until I freeze.
