The Asus P5N73-CM uses the Intel LGA 775/ Socket T CPU socket. Any compatible Intel CPU will have the same socket entry. It uses the aging DDR2 memory type, with maximum speeds of up to 800 MHz, and 2 DDR2 slots allowing for a maximum total of 4 GB RAM. DDR2 memory is exceptionally out of date, and considering how cheap DDR3 RAM is, using a motherboard with only DDR2 compatibility in a modern system build would be a very bad idea.

The UTX, or uATX form factor is analagous to the Micro-ATX form factor. The UTX Asus P5N73-CM should fit into all ATX cases, but its smaller size allows you to downsize your system build as a whole. Its size comes at the cost of features, so there are likely to be far fewer connections and expansion options available than in a larger motherboard.

The Asus P5N73-CM supports onboard graphics. This allows for integrated graphics when paired with a compatible CPU that supports them. Integrated graphics are a cheap alternative to using a graphics card, but should be avoided when frequently using modern applications or games that require intense graphical processing. There are 1 PCIe x16 slots on this motherboard. This means it is perfectly capable of accommodating the latest graphics cards, although it is important to try and use a graphics card with the same graphics card interface of PCIe v2.x, as anything below will not reach the motherboard's potential, and anything above will have its performance slashed to the bandwidth maximum of the Asus P5N73-CM's PCIe v2.x. The Asus P5N73-CM does not support multiple graphics cards via Nvidia SLI or AMD Crossfire.

The Asus P5N73-CM has 4 USB 2.0 slots but no USB 3.0 slots. While USB 3.0 slots are so far by no means necessary, and with a plethora of USB 2.0 peripherals to choose from, the USB functionality on this motherboard should be fine. With so few slots, however, you would have to use a USB expansion hub. As such, we would highly recommend a different motherboard, preferably with USB 3.0 functionality as well.
