As with all video cards, installation is a matter of placing the card in the PCI-E slot, connecting the power, monitor, and installing the drivers. Everything went without a hitch. The included driver CD had the latest nVidia drivers on it.
Normally, I really don't care whether a video card has instructions or not. Everything is pretty much self-explanatory, including the control panel. The Palit 9600GT Sonic has some features not on most video cards, and some instructions would be nice.
For example, someone with a home theater system might would like HDMI sound capability. There is a cable to accomplish this, but no instructions whatsoever, and I had no idea either. Take the small cable included in the bundle, plug the white end into the 2-pin connector on the video card, and the black end into the two close together pins on the S/PDIF out connector on your motherboard. There are three pins on the connector, two that are close together, and one that is away from the other two. The red wire should be connected to the inner pin, black wire to the outer pin. You should have the latest audio drivers installed, get them from your motherboard manufacturer's website, or the manufacture of your audio chipset.
The Palit 9600GT Sonic's fan is quite loud.for about the first three seconds into POST, then it quietens down to silence. I never heard it at all except when starting the system. The cooler keeps the GPU at around 42C at idle and 50C at load, which is very reasonable for modern GPUs, especially overclocked.
