How is the 7950 and 280x king when the 270 uses less power?

I think he is referring to KH per Watt

Yup... there are plenty of cards out there and integrated Intel GPUs that use less power... but aren't worth crap for their hashrate.

So the 7950 is still king when it comes to KH/s at its power consumption rate. Especially when you use one of Lantis' scrypt bin files for cgminer and if you undervolt with the .967v firmware.

We use rigs with 3 x R9 290 Sapphire and XFX cards. They get very hot though.

how hot ? I have some 7970 that hit 95 in an instant ... I've disabled them until I can get some fans on them

94 degrees. Need to add a tunnel for the airflow. That way i can cool them down to 84.

I'm running rigs with the same hardware, 3 x R9 290 Sapphire/Gigabyte/etc - and they easily get up to 94 as well. Looking at additional cooling to increase the has rate, and decrease the heat.

MiMiMiner, what sort of cases are you using? I'd be interested to see how you are tunnelling the airflow.

We use the Codegen 4U-500.
