Ruined you've once again told some one they made a mistake by purchasing an ATI based card and used ridiculous comparisons to try and show the nVidia card is the better card.
The truth is, I seriously doubt most people would even notice the differences showed in those comparison shots, when they are into the game.
I think what it is is you have very high expectations and expensive tastes and expect everyone else to feel the same way as you when the truth is most people 1) Can't afford the four or five hundred dollar video and 2) don't require the absolute BEST graphics to enjoy their games.
These are screen shots I took while playing Call of Duty on my P4 2.4 with a "piece of slow junk" Geforce 5500 video card.
It's not the best as far as graphics go, but it still looked damn good and it played without a single hiccup.
