nVidia Geforce GTX 650 Ti 1GB @ RWLabs
 

Like the GTX 650 that was quietly released last month, the GTX 650 Ti is built to deliver exceptional performance despite having an MSRP lower than $200. Nvidia has done this by giving the graphics card a 1GB frame buffer and reducing the internal Kepler architecture to fit into its respective $139 price segment. However, unlike The GTX 650, the GTX 650 Ti is built around the GK-106 GPU, which is the same core that powers the GTX 660. This means the GTX 650 Ti is going to be more powerful than the non-Ti version, and according to Nvidia we are talking performance that is up to 40% better.
