The M395X is the faster card, but the M290X isn't exactly a slouch. 500GB of storage also isn't a big deal these days with NASs and cloud storage.
The better solution would not to pay the Apple Tax and get a PC with the same hardware for a lower price.
Thanks for the info.
Afraid I'm already too deep into the pie to worry about a bit more Apple tax. Once your a member seems like they have ya for life.

well the m290x is based on a gcn1 pitcairn gpu and the m395x on the gcn3 tonga chip, so besides that the m395x is faster its also more efficient and has more features coming with its newer design. Therefor I would say the m395x is the more futureproof option.
