Can someone with FCPX & 2016 2.7/Radeon 460 Help?

[rawweb]

I picked up a stock configuration Radeon Pro 455/2.7GHz at the apple store the other day (obviously they didn't have the BTO options) and am very impressed with it so far. The only thing nagging at me is I didn't wait for a 460. I've got 13 days left to decide. My primary use will be graphic design (which this can handle) and video editing. I'm wondering if someone kind enough with FCPX and a 2.7GHz/460 could perform a BruceX export test for me? I know it's not the most scientific measurement in the world, but it will really help me weigh some things. Might even just decide to keep this and wait for some eGPU options.
