Not really a review, but I picked up the Asus CU model of the 280X when they were released, and it's a great card, but head to head the Asus 770 CU out-performed it, OCed better and ran cooler overall. (Great thing with the 280X was prices skyrocketing from the bit coin miners wanting them, I got a little over $100 more for it when I sold it then what they originally sold for
) Today the 770 is only about $20 more than the 280X and to me well worth it
