I never really mess with Anti-Aliasing because it is buggy on my computer and requires a lot of power even when it does work. I can get up to 2.0x-2.5x for Wind Waker, Twilight Princess and a few others, but more intensive Wii games like Skyward Sword and Mario Kart Wii with multiple players allow me to only get native resolution for a constant frame-rate. Depending on the game I adjust the resolution. So I'd think our settings should be about the same though your CPU is faster. I'm using rMBP, 2013, 13', 2.4GHz i5, 8GB RAM, same Graphics.
