I go from a 770 msi MSI has 970 turns a map .quoique wonders on some play as watch dog, or I had some surprise as a temperature of up to 72 degrees max. amazing !! whereas with the 770 I reach 72 degrees too. the cooling system is not more efficient. always on watch dog I have memory leaks with 970 while with my 770 I just lag problems. with 4GB on 970, weird seeing leak memory?
in short, the card remains a good msi card I advice gamer.
