New workstation for Premiere

Hi there,

I'm looking into a refurbished iMac Pro (mainly for video editing in Premiere, and a little bit of compositing work in after effects), and am choosing between a machine with the Radeon Pro Vega 64 graphics card vs a machine with the Radeon Pro Vega 64X. The only reason I hesitate on the 64X is because that gfx card is not on adobe's list of recommended cards for Premiere, but the 64 is. 

Im wondering if I should go with the 64 for that reason, even though the 64X is a better card. Any advice is appreciated. Thanks!
