Pros: Great price, great performance, serial based warranty
Cons: Gets a little warm, If you ever have to RMA with Asus....good luck.
Once I got them back, they were incredible. I can play BF3 with a single card on Ultra at 55+ frames, and 90+frames in crossfire. These two cards together will beat out a much higher priced 580, and come very close to a 6990.
The coolers on them are great, very quiet, the included software is a little....funky...to use, but very functunal.
If you are looking for some good GPU's for a great price (even at full price) These are right up your ally. If you are looking for great crossfire performance without breaking the bank, these are what you want.
