Just bought a second one to run in Crossfire with the one I reviewed earlier. I'm VERY impressed with the performance of these cards in Crossfire, for just around $200 my machine can finally play every game I've tossed at it with amazing detail. Bitcoin mining rate doubled (around 400 /mhs with very slight overclock) and these things don't flinch a bit under stress. I did have to upgrade my PS to a 750 watt, but everything runs like butter now. With a price like this, and 2 great game titles tossed in, you really can't go wrong for your money.


None, These are GREAT cards!

Other Thoughts:

It's normal for the top slotted card to run at a higher temp in Crossfire mode, so don't be alarmed that one card runs slightly hotter than the other. I've pushed these to 74C Bitcoin Mining and no issues whatsoever with perfomance, they run very cool while gaming.
