Digital Foundry Gives a Thumbs Up to Twilight Princess HD, Though There Are Framerate Dips

Sounds like they are saying its not because the GPU is too weak,
but because the system memory bandwidth wasnt high enough.

I hope Nintendo's NX is around the 176 GB/s memory bandwidth like the PS4's is, if they are aiming for 1080p.
