Am I getting the performance I should be?

[Jebisamess]

I'm running Dolphin 5.0 x64 on Windows 10. My system specs are the i7 6800k, watercooled overclocked to 4.2GHZ, GTX 1080 on air with a mild overclock, 32GB DDR4 @ 3200mhz and I'm running Dolphin and all of my games of an SSD. Basically I don't think I'm getting the performance I should be. I have V sync on and I'm forcing 16:9, for enhancements I have 4x native resolution (2560x2112) 8x SSAA, 16x Anisotropic Filtering, Forced EFB Copy, Per Pixel Lighting, Force Texture Filtering, and Disable Fog. I'm averaging 30-40 FPS sometimes hitting 46, sometimes dropping to around 25 usually close to 30. Is this the performance I should be expecting from a system of mine's caliber? I've seen some people say their 970 runs Dolphin just fine, and seen others claim even integrated graphics work well. I've seen people claim they can run titles at 4k with 60FPS, and my 1080 is struggling with 2.5k at 30. Any help would be appreciated. My monitor is 3440x1440 and I have Dolphin's fullscreen resolution set to that if that helps.
