Which HD 7970s are you using in Linux?

[debhead]

I'm trying to pick a 7970 for Linux. I was just going to pick one with an affordable one with high clock frequency, but there was a newegg review about the Catalyst drivers not working with the Gigabyte GV-R797TO-3GD. So I'd like to know, what is good that we know works in Linux? Or is this newegg review incorrect?

Thanks!
