The RAM is a given, yes.

SSD will only help load times, which will also affect some stuttering due to texture loading when doing large PVP battles or running around high-population capital cities.

With that in mind, I'd upgrade the video card first, then CPU, then SSD.

Not sure if you're aware but NVidia cards generally follow these rules:

* The first digit is the generation; second digit is what I call the performance category with higher being more powerful.
* 950 is faster than 750 > 650
* 980 > 970 > 960 > 950 > 940
* Usually, one previous generation of a higher performance level will be faster than the current generation at a lower performance level. So a 780 will likely outperform a 970, a 770 will outperform a 960, a 680 will outperform a 960, and a 580 Ti will dramatically outperform a 950 Ti (that last one I can confirm on systems I have built).

I refer to http://www.tomshardware.com/charts/g...s-cards,1.html when considering which GPU to upgrade to. You might be surprised at how affordable some of the previous generations cards will be.
