It's still worth it but in terms of buying new hardware right now it may be best to wait. It depends really on how much spare funds you can invest, another important aspect is if it will work out better just buying coins at the moment when the prices are relatively low.
It depends on what you are mining as well. There are some coins, not on whattomine, that are still 2-4 times more profitable that what is listed and known for a given GPU.
