they are good cards but you can buy a new 6870 for ~ 180 after MIR.. so I would think a used 5870 would be worth something in the $140ish range.
Except the 6870 is less powerful, and due to change in naming scheme, actually replaces the 5770 as opposed to the 5870. The 5870 was replaced by the 6970. I got an appraisal done on overclock.net, they are worth 200$ a piece in their current condition (dust free, fully reference design, transferable lifetime warranty).
So yes, WORTH roughly $200. Now to decide what I WANT for them…
