The 7970 ref looks alot like the 5870....a few 3Dmark test..I never really have went over 4.7ish with the 3Dmark cpu oriented test before..this 3930 will do it with ease..I stopped at 5.0...Im not totally sure how to clock it . right now just using the multi and it likes to run Vantage and 06 at 5.0....
