I would wait for the r9-290x anyway for price drops and get a top card, and the r9-290x might be the best bet for Crysis 3 and like games
Pretty much this.
If nothing else the new cards will lower the prices on other cards. I'd say a 290X or 780 (assuming its price does drop after the 290x launches) and sell your 7850 to offset some of the cost. I'd imagine you could still get between $100 and $150 for that 7850 if it's in great condition still. If the 290X launches at even $600, after selling the 7850 you could have only spent as little as $450 for a brand new, top-end card. Pretty good deal, imo.
So yeah, wait for 290x to launch, then decide.
