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.
