Given the choice, with AMD based cards, I generally choose Sapphire over MSI or pretty much any other brand unless there was a competing brand with a much better price at the time due to a sale or rebate. I'd personally go with the Sapphire card. I have that exact same card in another system, but it used to be in this rig, and it's quiet and performs well.
I currently have a Sapphire R9 290x which I'm also very much happy with.
