Can I upgrade my MAC for better fps?

[folkhav]

What I have:

Mac OSX 10.9.5
2.6 GHz Intel Core i5
16 GB 1600 MHz DDR3
Intel Iris 1024 MB

What the problem is:
running gamecube games is extremely slow. I get around 20 FPS if I'm lucky on games such as Twilight Princess.

What I want:
obviously to speed up my FPS (if possible). I'm looking for any fixes that are either free or cost at most $300, so I obviously can't just buy a PC. I'm not looking for something like "just close your other apps" or whatever, because that makes a difference of max 1 FPS. Some solutions could be: sending in my MAC for a gpu upgrade, adding a gpu manually, downloading windows and running that on my MAC, etc. Please offer any insight!

Did you try the latest Dolphin dev build or the 5.0-release candidate builds? They're faster than 4.0 stable

I just tried that and it made a small improvement. However, more graphics-intensive portions of the game still cause a low FPS (around 20). Other ideas? Is it possible, for instance, to sacrifice graphics quality for increased FPS (i.e. reduce the # of polygons being drawn/object)? Or if there's some setting/configuration in 5.0 that I need to change, let me know too please. Thanks!

Also I've noticed that the game seems to be running (when the FPS is normal, i.e. 30-40) in a seemingly x3 state. For example, Link walks twice as fast and the music is sped up, so I may have accidentally set some game-run speed to 2x or 3x what it should be. Would that cause the FPS to dip lower than it should be? And if so, how do I fix that? I didn't change any default settings when I downloaded 5.0. Thanks

Didn't help FPS, any other suggestions?

You can lower the IPC of the Wii's CPU

He means the underclock function in Config

How do I do that? And I'm not using a Wii, I'm playing the gamecube version.
