Gigabyte GV-N480UD-15I (rev. 2.0)

Gigabyte GV-N480UD-15I (rev. 2.0) are powered by NVIDIA GeForce GTX 480 GPU which supports NVIDIA PureVideo® HD technology, PCI Express 2.0 and Microsoft DirectX 11 and OpenGL 4.1. Integrated with industry's best 1536 MB GDDR5 memory and 384-bit memory interface and features Dual link DVI-I*2 / mini HDMI with HDCP protection.
Comes with Shader Model 5.0 which adds support for indexed temporaries which can be quite useful for certain tasks. Regular direct temporary access is preferable is most cases. One reason is that indexed temporaries are hard to optimize. The shader optimizer may not be able to identify optimizations across indexed accesses that could otherwise have been detected. Furthermore, indexed temporaries tend to increase register pressure a lot. An ordinary shader that contains for instance a few dozen variables will seldom consume a few dozen temporaries in the end but is likely to be optimized down to a handful depending on what the shader does. This is because the shader optimizer can easily track all variables and reuse registers.
