Best brand of gfx card to use?

[Sideways]

I don't mean to start a flame war of "MSI cards are the best!" But I am looking for suggestions if one brand of a card or another behaves better when overclocking, or running 24/7 for mining. I'm wondering because as I look for cards, there's always a price range for a certain GPU. Being your standard consumer, lower prices are typically better, but not if a $10-$20 more expensive card is going to perform better or live longer.
Any suggestions? One brand or another to stay away from?

I'd say it has more to do with the cooler mounted on the graphics card.

Stay away from those flat 1-slot 5770's for example. Nowhere near enough cooling power!

Personally i like Sapphires Vapor X cards. Because they can be OC'ed and they got efficient cooling.

I always pick XFX! They have double lifetime warranties.
