Mostly depends on your gaming. If you are one of those ppl who must jump in on the latest and greatest games, you'll definitely need to upgrade the gpu more frequently. As I'm just the opposite, I'm still enjoying games that are 5 years old, there's no rush or really any need to upgrade from a gtx970 on my 1080p/60Hz monitors. My 3770k never sees over 55% usage on anything, so that's good too.
