My system has Intel Core Duo E8500 3.16GHz, with Geforce Gts250 with 6gb ram. What do you think is causing my Fps?
What's your resolution that you are playing at and at what details? Looks like you are choking that video card at 1080p resolution and Very high graphics. Lower the graphics to low and it will be able to run at 20-30 fps. That video card is definitely not strong enough.
On GW2 under your settings choose the preset "Best performance". If your framerates dont improve, its probably time to upgrade. I know your CPU is within the recommended specs for minimum playing, idk about your gpu.
