Conclusion
Nvidia has continued to intelligently expand its Kepler graphics card series with this high-performance card. However, you'll want to avoid the regular models, which make a lot of noise, and go with a branded version.
Before releasing its new-gen graphics cards, AMD seemed intent on claiming the title of fastest model on the market. That has definitely been achieved with the Radeon HD 7990. This twin-GPU graphics card beats its competitors on performance, but it's not without its own limitations.
As was to be expected, with the GeForce GTX 650 Ti Boost, Nvidia has outed a well-rounded video card with performance that matches the competition. But be warned, for your ears' sake we suggest opting for a model with an alternative cooling system.
