You have a CPU bottleneck . The unlocked "k" version is recommended for demanding games , you will need higher clock speed (4.4GHz) than the default factory clock (3.4GHz)
a GTX 660 can handle up to 4x Internal Resolution , no AA , 16x AF . GTX 670 should be more powerful than that unless ....
_Your GPU was not perform at maximum performance ( not maximum usage but maximum GPU clock speed) . In other word , your GPU was at idle / 2D mode
Use Nvidia Inspector to check GPU clock speed when Dolphin is running . Make sure you set "prefer maximum performance" via Nvidia Control Panel (add Dolphin.exe to the list first)
Also use Realtemp to check CPU clock speed when Dolphin is running . Make sure your CPU doesn't underclock itself
