Gigabyte GTS 450 Overview
Gigabyte does use the reference PCB on the GTS 450, but has changed the color to blue.  Since this is the reference board the card is about 8.25-inches long.

The thing that sets this card apart from the reference card is the cooling system.  The reference card has a long heatsink and shroud that goes the full length of the card.  This card however has a smaller copper-core circular heatsink with a 80mm fan on top and a smaller black shroud.  Gigabyte says this design will keep the GPU 14% cooler.

Looking at the connectors on the card you have 2 DVI connectors and 1 mini HDMI.  The 6pin PCI-E power connector is located on the front end of the card.

If we flip the card over there really is not that much to see except for 4 128MB memory modules.  There are 4 more on the other side of the card as well giving you 1GB total.
