5170 - 5270 ... compare the price with the price 5 years ago ( I know it were the 5070 and 5970 at that time)
the 5170 is about 70% more expensive than the 5070 and the 5270 is about 60% more expensive than the 5970.
And I'm pretty sure the production numbers of the 5170/5270 are (much) higher than the Lemania based 5070 - 5970
Between 60 and 70% in 5-6 years is just insane.
