So im planning on buying a gtx 1070 , but my question is that how much better is it than for example gtx 980/980ti ? I have a gtx 960 atm so the change would be pretty big , but i play a lot of competive so i really need good fps in some games , and i dont feel like the normal 50fps in for example dayz is enough(and yes this is after the 0.60) . So is it worth it ?
