Youre stuck in the past. In 2006 a 8800GTX cost about 500$ and that was btw the high-end. And sure it cost a lot but to this day it still runs circles around both consoles duct taped capabilities hence high AA, AF, details and resolution for games. Someone would perhaps argue who cares about higher res, AA, AF and I would say most becouse otherwise console fans/gamers wouldn't be making constant comparisions between console titles.
It is interesting to note how well 8800 still runs most games out there (even newest ones) with high resolutions and all the bells and whistles turned on, considering the fact that it is more than 3 years old. Last generation, running HL2, Doom 3, and Far Cry on a Geforce 3 with high resolutions, close to max settings, and high AA and AF would seem out of question. This could be good or bad, depending on how you look at it.
