My reply to this comparison will be a bit long, so I'm interested to hear what you have found out already.
Well in The "Price Battle", the 7970 wins with a short edge.
I have read that the overclocking of the Asus is kinda small ( TechPowerUp), but it can reach 1250 MHz with a fan speed of 70% ( Tech Of Tomorrow Video said so :P )
I think both have great cooling, but I was really impressed with the boosted OC Asus one staying at 71 degrees with the 1250 MhZ at a fan speed of 70%., due to the DirectCU II cooling system.
But as specs, the Sapphire has bigger video memory , "more bits " ( 384 bit) , but according to a spec comparison page I read like half an hour ago, the Asus has bigger Memory Clock with 7010 MHz compared to 5700 Mhz ( or a number close to this I guess)
I'm still searching, so don't instantly think of me as a " fool' LOL
