Many enthusiasts build incredible computers that have large, expensive motherboard, fast processors, tons of RAM and one or more graphics cards.  The truth is, the enthusiast makes up for only a small fraction of computer hardware sales around the world.  Standard components sell to OEM PC manufactures in the 100,000's of units, where other specialty motherboards sell 10,000's of units.  The same is true of high-end graphics cards.  I know many people who have 7x00 series graphics cards from nVidia but I know of no one personally who has dropped their wad of cash on an 8800Ultra.

We are looking at a motherboard today from Intel that is designed and targeted toward the masses of regular consumers.  The board we are looking at is the Intel DG33BU, and this is based on Intel's new  G33 Express chipset.  Although the board comes in a mATX form factor doesn't mean it's short on features.  Overall, the feature list is pretty long for a mATX Intel motherboard.  We'll see that although this board is geared toward OEM's and people wanting to build a basic PC, it still offers good value and stock performance.


First Look:

The Intel DG33BU is a standard mATX board measuring 9.6" x 9.6".  Although the board measures quite small, the layout is pretty decent and there is plenty of room for vital components.  As you can see by clicking the picture below, the board comes with four DDR2 slots and can support up to 8GB of memory.  The large chipset cooler provides quiet cooling for the G33 Express chipset.  This chipset is responsible for 12 USB2.0 ports, four SATA ports, two Firewire ports and more.  The large aluminum cooler keeps things under control and should be excellent in most situations.
