6970 is just 12% than the 5870.
I'm assuming you're overclocking the 5850. The last time I tried on mine, yes, it was as fast as a 5870, considering the GPU was 1000 Mhz, and the RAM around 1350. Yet the card would still have slight stuttering, and didn't like putting on lots of AA. So far the 6970 is doing better with that. Also, I haven't installed the 10.12a hotfix yet. I'm expecting to see later drivers increase performance. It's pretty much how things were a year ago;
I almost bought a 4890 then because it was less expensive compared to the 5850, and performance really wasn't all too different, but I wanted something efficient, with better support. The arguments then also stated the speed difference wasn't huge. True, it wasn't, but later drivers improved on that. To sum up, most cards can overclock, so I may be able to take a low end card and push it up to a higher level, but that is not saying the higher level card can't go higher.
I've only encountered once, when I had a Ti4200, and a friend had a Ti4600. I could OC my card, and he couldn't, so our cards tied in performance. That was in 2003. I've not seen it before or after.
