==============================================================================

ASUS華碩ROG系列產品一直是許多玩家心目中的夢幻逸品，
相較於ROG系列主機板針對不同客群設計的多樣化產品，
ROG系列顯示卡的產品線顯得單純許多，終極目標就是打造最強的顯示卡!

這次睽違兩年半，終於再度推出採用AMD當前最強顯示晶片的ROG Matrix HD 7970顯示卡，
延續ROG Matrix GTX 580顯示卡的眾多特點，包括TweakIt即時電壓調整、
ProbeIt即時電壓偵測、MATRIX LED load Indicator 負載指示燈號、
GPU Tweak 專業超頻軟體介面與Safe Mode等功能，
另外還導入了可與ROG新款Extreme系列頂級主機板串接的VGA HotWire功能，
可透過OC Key即時監控電壓、頻率、溫度等參數，
以下我們使用頻率較高的Platinum白金版進行開箱介紹與性能測試。
