GeForce 940M vs GeForce GTX 660 Ti
When choosing between GeForce 940M and GeForce GTX 660 Ti, it is worth examining the specifications of the models in detail. Do they meet the recommended requirements of modern games and software? Storage capacity, form factor, TDP, available ports, warranty and manufacturer support are all important. For example, the size of a PC case can limit the maximum thickness and length of the card.
