16 gb/s bus?!?!
Wow, that's great, except for the 133 mhz DDR my system runs and the 166 mhz DDR a lot of people run!
That's piddling bandwidth for graphics card memory. The bus might be quick as anything, but it
don't make a darned bit of difference till you increase the
sytem bandwidth.
And if you just mean for faster communication between the CPU and the video card, that will mean an even smaller difference.
There's a reason AGP 8X doesn't give any noticeable difference in speed already and that's the same reason no one's seen fit to change the current standard for anything but marketing "8X."
