Product review (5 stars): Must have for 970 owners.
Wish I could have gotten this free with the deal, I missed it by a month.  Anyway this is a must  have in my opinion for anyone with a 970.  It looks awesome and really adds to the feel good for having such a high end card.  It also functions to cool the VRAM and the chip overall so it even has a functional purpose. This is important for this card in particular since the RAM onboard could stand to have better cooling.  I believe it works too because it feel warm or hot to the touch after the card has been used, indicating heat has been transferred to it.  It also adds much needed rigidity to the card and is very easy to install.  If you have a 970 and don't have the backplate, just get it.
