I have Lenovo W540 and Nvidia GTX780 Ti laying around (It was a gift to me by her since she replaced it with GTX 1070 on her gaming pc. I wonder why?), I plan to buy an egpu kit PE4C-EC060A V3.0 ( eGPU PCIe x16 interface for ExpressCard). I wonder, is it possible to just disable the quadro k1100m rather than uninstall it? I always bring and using my laptop for cad and v-ray rendering and the quadro dgpu is benefit for me when at work. I want to play high graphic games like Metro, Call of Duty, etc at home but the quadro is not benefit for gaming so I plan on building egpu and disabled only when gaming at home and enabled when I'm at working place.
