GeForce GT 545 vs GeForce GTX 660
When choosing between GeForce GT 545 and GeForce GTX 660, 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.
