Just wondering the difference in these 2 cards, including thermals. I think the Sapphire looks amazing, and I believe the xfx has better cooling. They have the same clock speed and pretty sure everything is the same. On the last gen sapphire it had a different cooling apparatus. Thanks for the comments
