I was going to upgrade my graphics card so I could play wow at maxed out setting then I noticed my processor was only running 1.8 ghz. Is it my processor that is caseing my computer to have bad FPS in game?

Notice your cpu is near the bottom of hardware they have listed. Your gpu isn't horrible by any means, but there are a lot of much more powerful cards out there.
Here is a link to the WoW Cataclysm performance guide done by Toms Hardware. It will give you an idea of what performance you will get at various resolutions, with a look at how CPU and GPU affect things:
This provides a good bit of food for thought and is probably a good hour of reading, but if you're considering spending at least several hundred dollars to get better performance mostly in WoW, then it's worth the time! Also, go NVidia if WoW is what you play the most.
