I'd go the CPU/mobo/DRAM then see how the new GPUs are and can start working towards one of them

You really can't do one without the other. Given there is no point getting a GTX 980 Ti with your current CPU, you need to upgrade your CPU, MOBO and RAM first. However, the improvement is only going to be minor until you upgrade your GPU too.
