GeForce GTX 660 Ti vs GeForce GTX 980M
When choosing between GeForce GTX 660 Ti and GeForce GTX 980M, 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.
