這次為大家帶來的是華碩RADEON R9 270 DirectCU II OC產品，華碩這次推出的R9 270除了採用高效散熱的DirectCU II冰霜酷銅散熱，預設時脈上就做了超頻的動作，超頻後的時脈為975MHz，比起公版的925MHz高達5.4%的超頻幅度，效能更能接近R9 270X。

https://www.xfastest.com/images/xftitle.png 結語
這張華碩 RADEON R9 270 DirectCU II OC，在OC的加持下縮短了與R9 270X的效能差距，在溫度表現方面相當不錯，在燒機過程風扇聲音算是滿安靜的，如果你是追求極限的超頻玩家，可以透過原廠附贈的小工具，把時脈再往上拉。
華碩這張顯卡價格約在$6000左右，原廠並提供人損保修與4年保固，在各方面的表現都相當不錯，不論在效能還是在散熱方面，都達到一定的水準之上，如果要選購AMD中階款的顯示卡，華碩 RADEON R9 270 DirectCU II OC是個不錯的選擇。以上資訊供大家參考
