Depends on what games you're playing and what resolution/quality you want to run them at. Are you unhappy with the performance you currently have?
warpfact0r10 brings up a good point. If you're current system is playing the games you want then there's very little need to upgrade just yet. If that is the case I'd strongly recommend that you wait until Zen hits, you'll then have more and better options. If you have a large budget a Zen build would be ideal. However if your budget is a little tighter you could pick up an FX-8350, AM3+ Mobo and some DDR3 dirt cheap.
I would say yes. Get something like a R9 380 and FX8320 and you should be good.
