Please insert dual core support and let the graphics unit more work

I just mean Dolphin even does not joke the Graphics!
Nearly everything is be working on the Cpu (?)
Maybe im wrong but you can have the same cpu with 2 different Graphics card --> lets say a 7950 GTX or a "slow" 5xxx series which supports Pixel shader 2.0 .....
Speed will be same!
Therefore im guess That everything its busting the Cpu !
Edit:
Forgot to ask for 64 bit support!
