Going Wireless on a Desktop

Hey Doc,

I’m looking to build a desktop computer for home use. I want to go as wireless as possible—wireless keyboard and mouse, wireless headset, etc. The only thing that should be plugged in to my computer is, of course, the power supply. Do you know of any Intel Core 2 Duo chipset–based motherboards that feature built-in Wi-Fi for smooth wireless home computing?

The Doctor thinks you should try your luck with an Asus motherboard. The company has been marketing boards with onboard wireless for a few years now. The P5E3 Deluxe Wi-Fi-AP@n, P5E3 Premium/Wi-Fi-AP@n, and P5K-E series all include some form of wireless integration that lets the boards act as access points or clients. Of course, integrated wireless isn’t the only option. You could simply pick up a PCI or USB Wi-Fi adapter for $50 and slap it into your existing motherboard. Ta da—wireless!

Asus’s P5E3 Deluxe Wi-Fi-AP@n is compliant with 802.11n, ensuring a speedy connection between the onboard wireless adapter and your router.

Asus P5E3 Premium

Motherboard naming conventions have never been easy to follow, but Asus threw us for a loop with its P5E3 Premium board. Is it an even better version of the stellar P5E3 Deluxe that we reviewed in January? Nope. The board actually features Intel’s newest enthusiast x48 chipset, which is, umm, 10 more than the x38 used in the P5E Deluxe board.

Besides the chipsets, you’d be hard-pressed to tell the difference between the two boards if they were laid side by side. Like the Deluxe, the Premium has integrated 802.11n wireless capable of running in access-point mode. Both feature a beefy heat pipe, PCI Express 2.0, an Analog Devices audio component, eSATA ports, and spiffy I/O shields. And like the Deluxe, the Premium also sports three physical x16 PCI-E slots, two of which run at x16 PCI-E 2.0 data rates while the third runs at x4 PCI-E data rates. For hardcore gamers, SLI still isn’t supported since Nvidia is limiting its multi-GPUs to its own chipsets. You can run CrossFire mode, but AMD graphics aren’t anybody’s first pick for gaming right now.

Also aboard is the Express Gate feature. It lets you boot into a mini OS that sits in a bit of flash RAM on the motherboard. From this pre-boot environment, you can browse the Internet or access Skype without having to start your OS. It’s an interesting concept, but you can’t save files from the browser. Such capability would make the Express Gate a great emergency tool should your OS get trashed and you need to access the Internet to search for a fix or download a driver or utility.

If the only change is the addition of the x48 chipset, should you upgrade from a P35 or x38? Not necessarily. The key change from the x38 to the x48 is official support for Intel’s upcoming 1,600MHz front-side bus CPUs; the x48 also adds improved Xtreme Memory Profile support, so boards can auto-overclock. Other internal tweaks give it better memory-ratio settings and better voltage control over DDR3 RAM. We must point out, however, that the x38 is perfectly stable on a 1,600MHz front-side bus and many other chipsets are as well. Like a Vulcan, though, Intel must do everything by the book. If it’s going to have 1,600MHz CPUs, it’s damn well going to have a chipset fully validated for it too.

Coming off the high of the x38-based P5E3 Deluxe board, we thought the x48-based P5E3 Premium would be just as impressive. But this board was just plain finicky out of the box, and we had to go through several BIOS requests from Asus to get one that would let us make basic BIOS setting changes. While the Deluxe version excelled against a competing 680i board in January, the Premium couldn’t outrun our XFX Nforce 780i SLI board here. The only numbers worth mentioning are surprisingly subpar disk I/O numbers and a performance edge in FEAR.

The Premium’s one serious advantage over Nvidia’s 780i is still pretty valuable though: validated 1,600MHz front-side bus support, which makes it a far safer bet for anyone who places CPU performance above running two GeForce cards in SLI. But who knows, maybe AMD will do Intel a favor one day by introducing GPUs that people will use.
