Im having problems selecting a gpu, so far from what i've gathered the Zotac extreme core has a 1228 MHz (base) 1380 MHz (boost) and the asus on the other hand got GPU (Boost): 1253 MHZ (Base): 1114 MHz. so does the Zotac make it superior because im having doubts of the card because its hard to find reviews/issues on several other websites. so far, both the cards cost the same from where i live
