Great reminder that there are 'gamers', and there are people who play games.
Unless you introduce yourself as 'Hi, I'm [your l33t hAXor nam3 h3r3], and I'm a gamer', most video cards priced over $75 or so will work, and current apple video like the 2600, 1900XT, etc. are just dandy. I went wild and bought a X1900GT for my PC last year at a stunning $200 to allow playing 'Supreme Commander', and it's a great card.
If you are that type who possesses 'f34r my l33t sk1llz' mojo, and have $500+ annually in video card spend, then go for it, and call cards in current production 'severely out of date', but it's just silly to suggest that there are no games to be played on the 950 or any of the card-carrying macs.
You may be right that there are no gamers on 950, but it's dead wrong to say there is no gaming on 950.
