NVIDIA GeForce GTX 650

The GTX 660 might be the entry-level flagship of the latest Kepler set of graphics cards, but their prices keep them out of the reach of most budget PC gamers. On the other hand, the GTX 650 is closer to being reasonably affordable at a price tag of $ 109. NVIDIA ’s xx50 cards have always been defined by budget prices with performance that knocks on the door of entry-level graphics cards – especially when overclocked. After taking the time to fully test the Kepler graphics card inside the GTX 650, we can say without a doubt that it continues the trend.

The GTX 650 is much more cheaper than the GTX 550 Ti as it costs $ 109. Compare this to the GTX 550 Ti, which came originally at a price of $ 149. Meanwhile, the AMD closest equivalent card is the HD 6770 which costs $ 129. The GTX 660 might be the entry-level flagship of the latest Kepler set of graphics cards, but their prices keep them out of the reach of most budget PC gamers. On the other hand, the GTX 650 is closer to being reasonably affordable at a price tag of $ 109.

The good news is, with the release of the GTX 650 Ti Boost, the GTX 650 's price is getting more discount. NVIDIA ’s xx50 cards have always been defined by budget prices with performance that knocks on the door of entry-level graphics cards – especially when overclocked. After taking the time to fully test the Kepler graphics card inside the GTX 650, we can say without a doubt that it continues the trend.
