HD6870/HD5830 - any coins worth mining

[vapourminer]

did a quick search but all i saw were years old posts about it.

have a HD6870 and HD5830, both 1 gig cards, from back in the BTC GPU days. just built up a test rig with the 6870 and i might as well mine something even if its more or less break even, cool temps are on the way here and a space heater for the basement may come in handy.

i mine eth with R9s but of course these cards wont cut it.

any suggestions?
