You might have to disable intergrated graphics in the bios?
milkshakez7z is right, you need to disable the integrated graphics and enable the dedicated graphics card. 3gb 7970 should rape GW2
Thanks! I switched from integrated graphics to PCIE in BIOS.
I'm still getting very low FPS in GW2, though, so I'm submitting a ticket to them (in case it's server-side).
