I'm looking to build a dedicated mining rig and found a cheap r9 290, but when I checked this website http://monerobechmarks.byethost5.com/index.php?i=1 that shows mining benchmarks, the ones for the 290 were all over the place. It ranged from 789h/s to 250 h/s. Any idea what I would actually be getting if mining with a r9 290?
Thanks!
