not really, 5850 seems to be beat a 285 but not by much... and a 5870 wont be 2x as fast as a 5850, i think we can all agree on that

On the other hand, in the comparison between HD5870 and GTX295, you can see that STALKER CS runs 38.4 vs 40.5 without AA and 24.2 vs 22.3 with 4xAA (so no 20% lower, even higher with AA) and Crysis warhead is 51.5 vs 53.6 and 43.6 vs 48.5 respectively (~3% and ~11% performance difference respectively) so...

In general, the difference between HD5850 and GTX285 (favorable to the Radeon) is equal or greater than the difference between GTX295 and HD5870 (favorable to the GeForce, if we don't count 8xMSAA results). So we could say that GTX285 is trading blows with HD5850 (favoring the ATi card) and GTX295 with HD5870 (favoring the NVIDIA dual card).

Of course, you should note that maybe a change from GTX295 to HD5870 is not so greatest performance wise (probably consumption, heat and price will be another thing), the same way that a change from HD3870 to HD4650 is not. If you want to see if changing from a dual high end chip configuration to the new generation is a gain, you should wait for HD5870 X2, or make an idea with a HD5870 CrossFire (wich here you can see how it scales, destroying a GTX295 SLI -as it's to expect given that the NVIDIA configuration is a 2x2=4 chips scaling, so much harder to scale).
i think you misread my post, i said:
upgrading from a 285 to 5850 doesnt make sense i think
upgrading to a 5870 maybe...
but from a 295 to a 5870 again doesnt seem to make sense, on the contrary...
5850 beats 285 but not by much
so going from a 285 to a 5850 doesnt really make sense...

upgrading to a 5870 MAYBE makes sense...

upgrading from a 295 to 5870 would actually be a step back... unless your just into benching and want hundreds of fps... where you really need extra gpu perf to get acceptable playable fps, ie demanding games, the 295 seems to be about the same or faster than the 5870.

but like i said, thats probably with amd cpu at stock speed... and as anandtech recently uncovered, some games seem to get a notable perf boost on nvidia gpus when bundled with an amd cpu for some reason... that might actually bite amd in their own pr arse in this document
