Gtx 970

Hey guys, i'm not a GPU expert so i'm going to purpose a question to the community for some help. I currently have an AMD 8350fx cpu with a HD 7950. I was wondering if it is worth the upgrade to a gtx 970? And will my cpu bottleneck the gtx 970? I'm mainly playing quite heavy games and it seems that my current gpu barely gets 30 fps on occasions :/

In most scenarios I would say your 8350 won't bottleneck the 970. But it would be a very good upgrade from a 7950.
