Pc lags, powerfull enough?

[brex]

I've tried messing around with many of the graphic and config settings, and I still can't get Wind Waker to play right.

I typically get around 18-23 fps, and choppy audio.

So my setup is

AMD FX 6120 @3.6ghz
8GB DDR3 1600mhz
Sapphire Radeon Hd 7950 3 Gb (overclocked to 1150mhz and 1400 memory clock)

Any and all help would be appreciated, thanks.

Or is it just Wind Waker?
