The 970 is a great card and its performance per dollar is unrivaled but you can not compare it to a 980. No matter how much you overclock it the 970 can not beat a 980 because that would be bad marketing. If an overclocked mid tier card can out preform the top tier card there is no reason for the top card. For a little more than the cost of the 980 you can have 2 970s in sli which will destroy games. The only problem for that is right now they aren't optimized in games and more than likely almost no new release titles will benefit from sli at time of release. In my opinion it is always better to get the best card you can afford and run 1 power gpu rather than 2 weaker ones
No, 970 with around 1500hz... Will be faster than a stock 980 In every aspect... My cousin have 970 amp extreme at 1500 and 1550 in boost (most of the time) and do better benchmark of my brother stock 980... In crysis 3 same story... So don't say bullshit a good 970 can beat easily a 980 STOCK...
😉 with air cooling... If go water can do 1600\1700hz with some cards
