Current Ranking of GPUs?

Well based on the reviews and performance of the 6850 and 6870 the typical

6850 (faster then 5830 not faster then 5850)
and 6870 (faster then 5850 not faster then 5870)

these statements seem to hold true SOMETIMES....however the crossfireX scaling of these cards seem better then the 5k series scaling....as well in some benchmarks it appeared the 6870 performed a well if not better then the 5870 and the 6850 was same if not better then the 5850...

but hell their prices smash the 5k series and all Nvidia cards

but anyways to the main point can we maybe compile a list of how current single card GPUs fit into the market for those of us looking to buy?

From my understanding its roughly

5970
gtx 480
5870
6870
gtx 470
5850
6850
gtx 460 1gb
5830
gtx 460 768mb
5770

? does this seem right at all?

i am currently in the market for a GPU and am looking at either the 6850 or 6870 both are great looking cards and good price...do u expect their prices to go up or down in the coming weeks? and also with the launch of the 6900 cards what do you think that will do to prices?
