Well I'm broke and even if I wasn't I couldn't afford something like that, it will probably cost as much as my entire computer. And I have to ask - whats the point? Say it allows you to play a game that has high demands at a frame rate of 200 fps. Whats the point of that? Could you tell the difference between that and something that cost half as much that gave you a frame rate of say 80 fps? I know its moving on with technology but this sort of thing comes at a huge cost and most normal people A - couldn't afford it and B - even if we could afford it we'd spend the money on the lower priced graphics and spend the remainder on something else.
Ask me in 3 years time and I might change my mind as games might have caught up with it.
Just out of curiousity, you aren't getting one or wanting one are you?
