Summary: Overall, I was expecting a lot from this card but was pretty disappointing. It runs considerably hotter than the GTX 670 Power Edition from MSi (my other card) and I can't OC it nearly as much as this one. I would recommend the PE from MSi, or the Direct CuII TOP card from Asus.
Pros: The GPU itself is very good, nice kepler design and all that. Boosts to similar performance of a GTX 680 even though it has around 200 less CUDA cores.
Cons: The Card itself is very poorly designed. Considering this is a very high end GPU, not to mention a "FTW" edition, I would expect the cooling to be a little better than stock. Even though it's not a bad design, the high clock speeds leave that card running quite warm, even without overclocking it....
Summary: First one was DOA, painless RMA and now on my 2nd, and it works like a dream I can play every game i own at max everything at 60+ FPS. The 4gb version is great, but im not sure about the advantages of the back plate. oh well. Well worth the money.
