I think it depends on your model size
Fits into 32gb: 5090
Fits into 64gb - 96gb: Mac Studio
Fits into 128gb: for now 395+ $/token/s,
Mac Studio if you don't care about $
but don't have unlimited money for Hxxx
This could be great for models that fit 128gb and you want best $/token/s (if it is faster than a 395+).
