Therefore making the 6870 a low end card when looking at amd's line up in its entirety.
Considering that over the past 6 months there has been no new games I'm aware of which would be graphically more intensive I'll have to point out that 6870 would be running games at as good graphical quality as before so I would not put it just yet in the "low end" part of the spectrum. It's ofc subjective, but considering one can still game quite fine even on 6670 or 6750/5750 cards then thats where I would draw the low end for gaming line. In my opinion 6850 and 6870 are still perfectly fine cards and I would put them personally into the bottom half of the midrange.

- as you can see main thing going for the 78xx series is the texel rate which means its subtantially better at doing AA, however, I also must point out that AA is a bit overrated nowadays (bcos of the relatively high resolution displays people use), as a human with 20/20 vision, sitting st ~75 cm from a 23'' 1920x1080 screen can not tell the difference between 0xAA, 2xAA and 16xAA without looking at the settings (this number is based on physical resolution of the human eye in the central part where it has the highest resolution - at that distance two pixels at such ppi will merge into one in the eye as they both end up on the same light sensitive cell in the eye, a "hardware AA" if you will in human eye. No point of wsting processing power on something what nature already does for you, eh?) Other than AA and compute performance the 6870 and 7870 are ~10% of each other.
