The Good Aggressive overclocking leads to record-setting application and games performance; tri-SLI 3D cards give you lots of headroom for games down the road; fast solid-state boot drive and plenty of secondary storage space; expertly assembled.

The Bad Most expensive desktop we've reviewed; service and support not quite as comprehensive as its boutique PC competition.

The Bottom Line Maingear's Ephex is the fastest PC we've reviewed, and also the most expensive. You can find better service policies from other boutique PC vendors, but the Ephex's overall speed and build quality are enough for us to recommend it to those in the market for the best desktop they can find.

Even though lots of vendors offer the capability, we've resisted reviewing a three-way SLI PC until now. Our hesitation had to do with a desire to keep the high-end PCs we reviewed at or around the $6,000 mark, hard to do with $1,800 worth of graphics cards alone. But last November our reservations were steamrolled by a crush of new technologies. Intel's expensive solid-state hard drives proved too enticing for gaming PC vendors, and by supporting triple channel memory, Intel's Core i7 chips invited loads of pricey high performance RAM. As a result, we agreed to review Falcon Northwest's $8,000 Mach V back in November, and it's also why we let Maingear submit this triple-SLI $8,798 Ephex desktop. That price makes this Maingear the most expensive desktop we've ever reviewed. Provided you have that kind of commitment to PC gaming, you'll find the Ephex delivers an exceptional entertainment experience.

By giving the Ephex a $4,600 price tag for its most basic configuration, Maingear seems to be making a distinct effort to put its flagship PC out of reach for most gamers. And as expensive as it sounds, even our $8,800 model lacked features such as a mouse and a keyboard, a monitor, or extras such as a Bigfoot Killer NIC, a Wi-Fi adapter, or speakers. On the flipside, you can shed $1,100 off the price of the system if you opt out of the fancy paint job and the transparent side panel. None of this is to say that value is a primary concern in reviewing this PC, but if all you care about is clean design and performance, you can get all of this configuration's core functionality for less.

Like most boutique PC vendors, Maingear pays special attention to the design and wiring of its systems, and if the build quality of this Ephex is any indication, Maingear has shown that it can rival the meticulousness of Falcon Northwest. The liquid cooling plates on the graphics cards hardware obstruct the free card expansion slots, but that's our only major complaint. Adding hard drives is simple with outward facing drive bays, and overall both the external and internal appearance of the system show that it was assembled with great care.

It's almost silly to talk about this system from a value standpoint given its price tag, but we'll do it anyway, comparing it with Falcon Northwest's recent Editors' Choice winning Mach V. One of the complications of reviewing PCs in this price range is that by assuming potential buyers have the means to spend near-unlimited funds to get the best hardware, it's easy for one vendor to trump another by simply ensuring that its rig has more features than the last high-end PC we reviewed, regardless of cost.

For the sake of making this an apples-to-apples comparison, we configured a Mach V from Falcon as closely as we could to the Maingear Ephex and came up with an $8,753 system with two GeForce GTX 295 cards (which are also an option from Maingear). Falcon has no tri-SLI option, and without testing we don't want to speculate which configuration would be faster. Suffice it to say, we find Maingear's asking price for this system right in line with similar configurations from other vendors.

That brings us to performance. As you might expect, the more aggressive overclocking, the speedier memory, and the powerful graphics hardware serve the Maingear Ephex well on our benchmarks compared with the Falcon Northwest system. The Cinebench test provides evidence that you really do get more performance from the Maingear's more aggressive overclocking. Because overclocking is tied so closely to the specific tolerance of each individual CPU, the speeds on display here may vary from both vendors in any hardware you purchase. In either case, by overclocking Intel's already impressive Core i7 965 Extreme Edition chip, both Maingear and Falcon Northwest have produced some of the fastest benchmark scores we've ever seen.
