I'm happy that you're getting 360+ MH/s on your Asus HD7870DC2-2GD5-V2 gpus. The Fedex dude was just here a couple of hours ago to deliver two of exactly the same cards that you have to replace a couple of mining-challenged Nvidia GPUs on an old gaming rig. I have come to the conclusion that generally, AMD cards that are moderately OC'd, usually hashes around 26% of the number of stream processors. So I figured that I would be getting around 265 MH/s (26% of 1024 stream processors) out of each of these cards. At what clock are you getting 360+ MH/s with, may I ask?
7850 - I got about 330MH/s - 1200Mhz
7870 - 430-450MH/s - 1215Mhz
7950 - 540MH/s - 1150Mhz
7950 - 520MH/s - 1100Mhz
interesting you post that cause thats about what i get on my 7970 at stock clock
about 530-550mh/s
and 26% of 2048 is 536.48 so its workable
