For casual gamers - that I'd expect. I, too, can't afford $300 very well. My next upgrade is probably windows 7 (maybe 8 if it gets that far out), but will take a good fraction of a year to save up for it.
However, I didn't think such low end cards would get 30 fps in any of today's games with those kinds of settings as that link covers. I don't know that game so it's extremely difficult for me to gauge anything. I only know console games from the previous generation and earlier, so I'm far, far behind in gaming in general (2006 is the year of the newest game I have). Zapper is the newest game I played on my computer, but I lost my save file (with 1300 lives too) since I reinstalled Windows later on and I've since lost all interest in computer games, but not console games (2400 hours on 2 Disgaea games in less than 2 years is crazy).
I know what antialiasing is (this makes the otherwise sharp, pixilated edges smoothed out by making the pixels on the edges transparent). I know what frame rates are (the higher, to a certain point (typically 60), the better as it results in smoother motion and better and more precise control). However, I have no idea what anisotropic filtering is or what kinds of settings are present in computer games (besides, perhaps, audio and control configuration). Thus, I have too little to go by to determine anything.
