Hello all same problem here on amd , all worked well , got a psu back as RMA from Corsair (sent TX650 v2 to them and got a TX650 non v that made a sound , i think I have a record with it . Bought msi r9 390 and w10 . After some days , pc had no psu , installed r9390 and new psu TX650 and then windows 10( from a w7 illegal installed in 2013 with almost no updates) .As the new psu made a bad noise like a fan broken (don't know if it was the fan) I mounted my ga 6870 thinking to protect my r9 390 . Didn't played any games , in 2 days sent tx650 again to rma , and in 2 weeks got RM650i from corsair . Now Lod and tearing and flickering in grass and troops is bad : shogun 2, guild wars 2 , rome 2 , eso online . Tried with another 2 psu, one new mb and another cpu, no improvement. Installed w 10-14 times .

here someone says it could be cpu cache
this reflects best the pixelation in trees :
