How well can this new iMac run Dolphin?

Hi everyone. I'm planning on buying a new iMac in the near future and I'm wondering how well it can run Dolphin and how far graphically I can push it. Here's what it will have:

Model: iMac (27-inch, Late 2013) iMac14,2 ME089XX/A
Processor: 3.5GHz Quad-core Intel Core i7, Turbo Boost up to 3.9GHz (Haswell)
Memory: 32GB 1600MHz DDR3 SDRAM
Storage: 512GB Flash Storage
Graphics: NVIDIA GeForce GTX 780M 4GB GDDR5

Thanks in advance.
