Overall, the Intel HD i5 660 has poor performance. This is not altogether surprising, as it is an integrated GPU. If a robust graphical system is desired, a dedicated graphics card upgrade is a must, though you can get away with an integrated GPU for less intensive applications and games. This integrated GPU is now over 11 years old, which means it is extremely out of date and is based on very aged technologies. This integrated GPU will be dwarfed in performance by its modern counterparts, and will likely have very little driver support from Intel. The GPU is not too power-hungry at 73 Watts.
