The GTX 650 Ti was our favorite $100 - $150 graphics card last year, as it thrashed the Radeon HD 7770, its direct competitor. Then last month AMD decided to attack the $150 price point with a new HD 7790 GPU, but the reaction didn't take long to arrive.

Just a week later Nvidia officially countered by releasing the poorly named GeForce GTX 650 Ti Boost, now the third graphics card to carry the GTX 650 name. At $170, the GeForce GTX 650 Ti Boost sits between the Radeon HD 7790 and the 7850. In terms of performance, we actually expect the GeForce GTX 650 Ti Boost to be a lot faster than the GTX 650 Ti, even when it's based on the same GK106 architecture.

It's been over six months since Nvidia launched its Kepler architecture and we've finally seen the GTX 600 series enter more affordable price brackets, delivering a greater value every step of the way.

Having attacked the mid-range and upper-end markets, Nvidia has its sights set on the sub-$200 range, unleashing its GTX 650 Ti. At $150, the new arrival is roughly 34% cheaper than last month's GTX 660 and about 7% pricier than the Radeon HD 7770, which fetches around $140 depending on features and rebates. Here comes our full review.

With most board partners scared to push the 244w GTX 580 far beyond its reference spec, we were surprised when Gigabyte announced its solution which treads on deeper water than the competition dares to.

The Gigabyte GTX 580 SOC operates at 855MHz or about double the overclock of Asus and Zotac's cards. For what appears to be a justifiable $35 premium over Nvidia's already steep $500 suggested retail price, they are adding a new PCB design and upgraded cooler.
