I have 5850cf which is basicly 5970 and will probably buy 680. Hate crossfire for all the problems it have. Have checked around myself and in techpowerups test 680 is 16% better than 5970. Their test is a bit wierd do as 5970 is better than 680 in shogun 2. Have tried myself by comparing to a test where i know the settings and my cards get 48fps and 680 get 60fps. so about 25% difference. the 680 is also much better in bf3.
Have always thought that techpowerup get some wierd results sometimes.
