Would anyone be able to help me with the website? I want to list the hash rate range (in scrypt-N and scrypt) and the power usage for the card we are selling. Can anyone help me determine the correct values for :

Sapphire r7 240 2gb ddr3 with boost
Gigabyte r9 270 2gb
Sapphire Toxic R9 280x 3gb

I get around 480kh on regular scrypt and 220-240 on scrypt-N on my 270's. Power usage is approx. 160w per card.

What settings are you using on your 270s? I'm having problems getting above 200.

To be honest, I have had a time with getting them stable with Vertminer. Its really weird, my home system (1 270x, 1 270) will run for days no problem using the version called VertiKev, which is based off 0.5.2, using settings below, running 2 threads per card.

"rawintensity" : "5120",
"worksize" : "256",
"gpu-engine" : "1130",
"gpu-memclock" : "1500",
"thread-concurrency" : "6336",

This yields 242kh on both cards. But I have a 5 GPU rig with 270's and another 6 GPU rig with 270x's at my store and neither will run stable on those settings. Crashes usually within 30 minutes. So I have tried lower intensity settings, which have helped. But usually only get around 220kh max and it still is not 100% stable. Will run for hours at times and then other times will crash several times a day. Have tried 0.5.3 on those systems too, running 1 thread, with similar results. So I am still tweaking on those. If I am going to continue mining scrypt-N coins, have to get them more stable. I would try the settings above first though, they run stable for a lot of people just like it does on my home system. All of my rigs will run regular scrypt for days at around 480kh, just have to get Vertminer that stable.
