Gigabyte added a new SKU (GV-N950D5-2GD) based on the GeForce GTX 950, this is the OC model. Armed with 768 CUDA Cores and a 128-bit memory interface the product comes at a core clock of 1026MHz & a boost clock of 1190MHz.
There's also an OC mode which overclocks it further to a core clock of 1051MHz & a boost clock of 1228MHz – OC Mode and a 2GB of GDDR5 memory set @ 6610MHz. This requires OC Guru software to run at all times.
The card is cooled with Gigabyte’s custom 90mm cooling fan (w/ air flow optimized cover and aluminum base) that can dissipate heat effectively from the GPU while keeping the fan at lower speed and noise, and provides a number of output ports: 1x dual-link DVI-I, 1x dual-link DVI-D, 1x HDMI and 1x DisplayPort.
