The release of AMD's 780G chipset was a big step for integrated graphics. It proved to be the best gaming IGP released to date, showed great proficiency in playing high definition video, provided a multitude of output options, and delivered it all with high energy efficiency and a low price-tag. The new Hybrid Crossfire feature also assured that the IGP would continue to make a contribution even if a discrete ATI graphics card was installed. With 780G, AMD became the platform of choice for those on a budget, but demanding good value.

As far as we know, none of Intel's IGPs come even close at this ttime. nVidia has also been slow to react, with the majority of their mATX motherboards still based on the aging Geforce 6100 chipset. On the AMD side, they seemed to have skipped the Geforce 7 series altogether. The Asus M3N78 Pro under scrutiny here is one of a new series, powered by the new Geforce 8300 chipset. Its IGP is based on the Geforce 8400GS and supports all the latest standards including HyperTransport 3.0, PCI Express 2.0, and video features like DirectX 10 and Shader Model 4.0. Its PureVideo HD decoding technology can fully decode H.264 and VC-1 (Blu-ray) content, leaving the CPU more free to perform other duties.

Last but not least, the 8300 chipset supports Hybrid SLI — nVidia's answer to ATI Hybrid Crossfire. When combined with an entry-level nVidia graphics card, it can work in tandem with the IGP to boost performance. When partnered with a high-end nVidia graphics card, the card can be shut off completely when its services are not required, or so they claim. The M3N78 Pro is perfectly suited for the later feature, as it is a full-sized ATX board — the defacto choice for high-powered PCs.

The M3N78 Pro box has a semi-reflective coating. It's not humongous.

The accessories.

The M3N78 Pro comes with IDE and floppy cables, two SATA data cables and two SATA power adapters. DVI is available via a HDMI to DVI dongle and VGA through a PCI bracket with a cable that patches into a connector on the board. A manual, support disc, I/O shield and Q-Connector kit round out the accessories.
