*GeForce GTX 660 Ti supports PCI Express 3.0. The Intel X79/SNB-E PCI Express 2.0 platform is only currently supported up to 5GT/s (PCIE 2.0) bus speeds even though some motherboard manufacturers have enabled higher 8GT/s speeds.

1 - NVIDIA 3D Vision Surround require two or more graphics cards in NVIDIA SLI configuration, 3D Vision glasses and three matching 3D Vision-Ready displays. See 3D Surround for more information.

2 - A GeForce GTX 660 Ti GPU must be paired with another GeForce GTX 660 Ti GPU (graphics card manufacturer can be different). SLI requires sufficient system cooling and a compatible power supply. See the list of SLI-Certified components for more information.

3 - 3840x2160 at 30Hz or 4096x2160 at 24Hz supported over HDMI. 4096x2160 (including 3840x2160) at 60Hz supported over Displayport. Support for 4k tiled MST displays requires 326.19 driver or later.

4 - Support for HDMI including GPU accelerated Blu-ray 3D support (Blu-ray 3D playback requires the purchase of a compatible software player from CyberLink, ArcSoft, Corel, or Sonic), x.v.Color, HDMI Deep Color, and 7.1 digital surround sound will be added in a Release 260 driver. Upgrade your GPU to full 3D capability with NVIDIA 3DTV Play software, enabling 3D gaming, picture viewing and 3D web video streaming. See www.nvidia.co.uk/3dtv for more details.
