Will 8GB ram on the 390's beat out the 4GB ram on the Nano / Fury's in ZCash algo?

I've been eyeing zcash. It seems like it could be the next PoW coin. I'm curious as to if the 4GB of ram is going to create a bottleneck on the Nano / Fury's since supposedly it's limited to 1GB ram per thread. My understanding is that this is also partially limited by ram bandwidth which obviously the 390's are behind the Nano / Fury on.

I'm toying with the idea of building a few more miners based on pure speculation but don't know if the cheaper power hogging 390's are going to actually have better hash with more RAM or if the bandwidth will be the limiting factor. Any ideas?
