I am not sure an upgrade will do much for your performance. I have a similar setup to the OP (though my gfx card is a few models higher) and my CPU rarely gets above 60% load and my GPU on the GFX card is rarely above 30%. Even while with these light loads, like Lando above, I occasionally get down to 5fps. I dont have difficulties with fps or lag in other MMOs so I dont think it is ping related either. I suspect the main culprit at the moment is the new net code that CRS are beta testing which is trying to sync all the action together. Note: I have noticed that when there are a lot of aircraft around the fps drops but this may just be coincidence.
