The doubt of the 8s

Hey guys, I'm planning to buy a htc 8s, but I have my doubts about this. Will the phone, packed with 512 MB's of RAM and clocked at 1 Ghz Dual core snapdragon s4 be powerful enough? I know that WP is totally different compared to Android which will need you to buy a phone with i7 processors, but does the 1 gigahertz the trick? Or will it be on the edge? What do you guys think?
