After that you're stuck between the stock cooling solutions from XFX, Gigabyte and MSI. I don't know why you'd stray away from Sapphire, they're the best AMD AIB there is.
may seem like a dumb reason but they screwed me out of a 15$ rebate i still might be willing to buy from them but as a last resort and only if i could buy a card from them at the same price as other cards with rebates
Why worry about it at all? The 5770 isn't a hot card.
well iv always bought sapphire so never really payed attention to other brands now that sapphire is at the bottom of my list i dont know which brand is good so im buying based on price and which ever one has the best features which to me better cooling
