Based on Intel's P965 chipset, the ASUS P5B Premium board suits any of the current generation Intel LGA775 socket-based CPUs and can also handle an ATI CrossFire dual graphics card configuration. It comes with some features that aren't found on most motherboards, performed reliably in our tests, and its installation was almost a no-brainer.
- Reliable performance; added features, such as ScreenDUO, an array microphone and AI Remote, are useful; eSATA; supports CrossFire.
- It could use one more PCIe slot and one less PCI slot, the supplied ScreenDUO driver didn't work .
The ASUS P5B Premium has glut of features, performs well and is well built. If you're after a motherboard for a Vista-based Intel system, this is a great choice.

The P5B Premium is a solid foundation for any Windows Vista-based PC. We didn't even have to install chipset drivers after we installed the operating system; Vista recognised all of the board's components, save for the audio chip, which we had to install from the driver disc.
Physically, the board is well built and has a layout that's easy to work with. The spacing of the components allowed us to easily install our Core 2 Quad QX6700 CPU with a standard heat sink, 1GB of DDR2 800MHz RAM and a GeForce 7600GT-based graphics card. Along with a 150GB Western Digital Raptor hard drive, this configuration propelled the board to a score of 101 in WorldBench 6, which is a few points shy of what we were expecting.
In the Cdex encoding test, where we convert 53min worth of WAV files to 192Kbps MP3 files, the board took 1min 49sec, which is an expected result for our configuration. Preset overclocking options are available in the BIOS, which allow the system to be overclocked dynamically (up to 20 per cent), but you can also manually adjust the front side bus speed and the clock ratio of the CPU. We overclocked the CPU to 3.3GHz, and the Cdex encoding time was reduced to 1min 35sec.
Heat sinks and a heat-pipe keep the chipsets cool, while the CPU fan is controlled by ASUS' Q-Fan 2 technology (it speeds it up when the processing load is high and slows it down during idle times). The board proved to be reliable throughout our tests and we didn't experience any instability problems during multiple 24-hour test periods. All of the board's added features - ScreenDUO, an array microphone and AI Remote - worked fine, but we had to install updated drivers for ScreenDuo to work. The ScreenDuo feature is something we haven't seen on other boards. It's a separate LCD screen that plugs into a USB port and can display system information, photos or text notes. It can also be used to control music through Windows Media Player. We found it useful for monitoring the CPU temperature and fan speed.
The Array microphone picked up a speaking voice at normal pitch clearly from about a metre away, which can be useful for talking online via Windows Live Messenger, for example. The AI Remote works via infrared and can be programmed to launch applications and control the playback of videos and music. It's a little fiddly (for example, the Windows Media Player window had to be active before the control functions would work for it), but useful.
The P5B comes with an abundance of USB and SATA ports (eight and six, respectively), two FireWire ports, two gigabit Ethernet ports and one eSATA port, but it only has one IDE port. It has three PCI slots, one PCI Express (PCIe) x16 slot, one full-size PCIe x4/x2 slot and one PCIe x1 slot. That's one PCI slot too many and one PCIe slot too few for our liking.
