Which HD 6850 for mining?

[Dark Shroud]

Ok I've never bought an after market cooled card like either of these before.

I was going to order today two HD 5830s today from Newegg. Imagine my surprise finding them sold out. And now Newegg, Tiger Direct, & Amazon are out of the properly priced cards. Also everyone else trying to price gouge on used cards can go to hell. AMD is going to have a great year.

So which of these cards would be the better deal? I'm leaning towards the Gigabyte card since its factory OC'd. I'm not familiar with Asus's Smart Doctor software at all. Does that change the cards's settings on the fly?

If you can recommend a better AMD card I'm open to suggestions.
