If you see an FX camera in your future, I would say yes to buying FX lenses. A DX sensor will use the center of the FX lens since the FX lens covers more than DX sensor and you will get better corner to corner sharpness on the DX sensor. The FX lenses are more expensive and heavier than the DX lenses. I believe you will also have better access to faster lenses in choosing FX lenses. Also better IQ, just my opinion, with FX lenses. Specifically the 24-70 f/2.8 and the 70-200 VR II f/2.8, again just my opinion.
