Well ,to be honest, after reading all this "I would call them cards as.." posts, im beginning to see the light with amd chosing.
Taking into account price/performance/features and NOT renaming 5770s ,its clear AMD had a tough nut to crack with naming these, they are to similar to 58xx to call them 5700, 256bit bus for example, different price segment too.
It aint to pretty, but AMD had to do this taking cayman into the equotion.
Price on these looks really good.
And really , all "recommendations" from users here look worse on the whole :P
