It's great in the hands of a highly skilled performance aware programmer. Most game developers are not highly skilled and performance aware.

Alternatively, one might say "Show me a console with 6GB of REAL memory capacity"...

It's not hard to get memory bandwidth if you are willing to sacrifice capacity and flexible configuration.

Consoles and PCs are aimed at very different targets. I mean, Intel did try and make PCs with Rambus memory once upon a time - what did you think about that back then?
