Unsadisfactory frame rate. Software, hardware or setting?

Let me make my problem more clear. To have Mario Kart play at 60fps with little to no abrupt drops in frame rate I have to use HLE audio, 2xIR, no AA and all the speedhacks:
Skip EFB access
Ignore format changes
EFB to Texture
Texture cache to fast
XFB disabled
Fast depth calculation
Disable per-pixel lighting

Anything less, say up the IR to 2.5x and I am playing sherbet land at 50 frames and all the jittery audio that comes with it. This isn't even remotely better performance per setting I was getting with a 3570k @ stock and gtx670. I am now running of far better hardware and performance seems to be lower.
