I care, I always like faster graphics.

You're probably overgeneralizing. Actually, I run games on my server and display the graphics on my laptop. It works. I'd be happy if it was faster.
I don't see right off how AIO would make that happen though. Ben, could you please enlighten me, what would be the mechanism? Are other OSes doing X with AIO?
