I would stick with what you already got too. Those cards are still epic. My rig is new so I figured I go with whats current. If I had the money I would have gotten at lest one 7970, then waited for them to drop in price and get another to crossfire, but the lone 7770 is running like a champ. Most likely what i'd do is get another 7770 run that in crossfire until the next gen cards come out, and get a 8970 lol, then again I do wanna make another build so the 7770's would still have a home lol.
