Polywell Poly i680SLI - Core 2 Extreme QX6700 2.66 GHz

CNET editors' review

Last week we got a crack at a few new PCs with Intel's new Core 2 Extreme QX6700 quad-core chips. This week, we have the quad-core Polywell Poly i680SLI, which has the new chip as well as Nvidia's latest, the next-gen GeForce 8800 GTX graphics card. This potent combination of high-end parts makes Polywell's new PC the first we've seen that looks truly ready for next-gen gaming. It might be a little while before you can put all of the new hardware to the test, but while you wait for the software to catch up, you should be able to shred through current-generation games at the highest possible resolutions and with maximum detail levels. And the best part is that Polywell has put a semi-approachable price tag on this PC. For $3,799, you can have one of the fastest gaming PCs on the block today and be ready for the games of tomorrow.

On the outside, the Poly i680SLI doesn't look that remarkable. It has a generic third-party chassis that has some awkward design elements. Its power and reset buttons and all of the frontside ports hide behind an unnecessarily bulky plastic door that sits on the machine's upper front edge. And its fan ports, including the massive 120mm side panel vent, come with blandly stylized plastic trim. Perhaps using an uninspired case helps Polywell keep the costs down, but even a nice case would add only an extra $100 or so.

Inside, Polywell paid a bit more attention to the Poly i680SLI's appearance. The hard drive and the optical drive cables are mostly tied down and routed out of the way. Polywell opted for the "stash the power supply cables in the empty drive bay" approach, which always looks a little sloppy, but at least the power supply's cables are bound in mesh.

The Poly i680SLI's basic specs include a 2.66GHz Intel Core 2 Extreme QX6700, a 768MB GeForce 8800 GTX 3D card, two 150GB 10,000rpm hard drives, and 2GB of 800MHz DDR2 SDRAM. All of those parts are plugged into Nvidia's latest high-end motherboard chipset, the i680SLI. Polywell played a conservative hand here and didn't overclock anything. That's probably a smart move. We've heard from various PC vendors that they're happy with the GeForce 8800 GTX's stock heat spreader, but if you touch the card while it's running, it feels very warm even at its stock speeds.

We're not too worried about the lack of overclocking given the Polywell's performance. On our 3D gaming tests, the Poly i680SLI and its single GeForce 8800 GTX card beat two heavily overclocked PCs running an ATI Radeon X1950 XT CrossFire setup, each with two previous-gen $500 3D cards. The only system that was faster was Dell's XPS 710, and that comes with a previous-generation Nvidia Quad SLI setup. For all of the Dell's raw horsepower, it doesn't support the image quality and next-generation features of the Polywell's single GeForce 8800 GTX. You can make the argument that there are no games that will really challenge the GeForce 8800 GTX card today, but if you can get this kind of performance and be ready for next-gen titles when they hit next year, there's almost no reason not to buy this system now.

If you're wondering why we might argue against the Poly i680SLI, you have to look a little deeper. Due to its Nforce i680SLI motherboard, this PC can, in theory, support two GeForce 8800 GTX cards in full, dual-x16-bandwidth SLI mode. That would clearly be overkill for any game available today, but we expect that cranking up a next-gen game, such as Crysis, on a large LCD would probably put that extra horsepower to use. But with the Poly i680SLI's 700-watt power supply, we wouldn't recommend it. Neither would Nvidia. For two GeForce 8800 GTX cards in SLI mode, Nvidia suggests at least a 750-watt power supply. The configuration Polywell sent us is about 50 watts short. Polywell will offer a 1,000-watt power supply, which should do the job, but it will also add to the cost.

That actually leads us to a point that's in the Polywell's favor. Because its 3D performance is so strong with just a single card, you have lots of room for upgrades. The Nforce i680SLI motherboard has two spare PCI slots, as well as another x8 PCI Express slot. That means you can add a sound card, a TV tuner, and a physics card, either after the fact or on Polywell's configurator, if you wanted to make this system as fully loaded as you can. There's also room for two more memory sticks, as well as one more hard drive.

The Poly i680SLI comes with Polywell's standard one year of parts-and-labor coverage, as well as 24/7 phone support. Polywell's Web site remains a jumble of links and poorly organized help documents. You can find some of what you're looking for if you squint hard enough. Polywell maintains a serial number-based tracking system, however, which presumably will help expedite over-the-phone issues.
