http://www.3dmark.com/3dm/4070463 - is this score ok or should I return the card? i have ghz edition from gigabyte, but i had to reduce some core and memory clocks(factory !) , because i am getting dx errors in bf4 after few mins of gameplay, i was getting same errors on my old hd 7950 when i oced too high, also my temperature reached 75°C after the test, but i read somewhere safe temp is somewhere at 90°C so i guess i wont be worried
