Everyone needs 12gb of frame buffer :-)

I have always been a PC gamer. Not that consoles aren't good enough. I think games ought to be played in a nice chair on a 60 inch TV screen - not leaned forward over a keyboard. But I like good visuals and to be able to tweak stuff, visuals as well as UI and configuration files. And now Nvidia has announced its latest $3000 monster GPU: Titan Z. Do I have to get it? I don't think so, but part of me wants to say: Does the sun rise in the east?
