The Good Stable overclocked CPU; well-thought-out component offerings online

The Bad More expensive than faster, better-equipped competition; no Blu-Ray drive; some might consider power supply too close for comfort to add second dual-chip graphics card.

The Bottom Line Digital Storm's 950Si has all the makings of a quality performance gaming system, but its value proposition comes up just a bit short. The stable-yet-aggressively overclocked CPU tells us that Digital Storm knows what it's doing, and with a more competitive price it would earn a more enthusiastic recommendation.

Editors' Top Picks

The $3,636 950Si is the first PC we've reviewed from Digital Storm, and for the most part we've come away impressed. The system itself came with an overclocked, but more importantly stable Intel CPU, and but for a minor design flaw it seems competently built. Digital Storm could have pushed harder on both the performance and the value offering of this system, as AVADirect's Editors' Choice winner from a few months back gives it a tough time on both fronts. If you're willing to wade through Digital Storm's cumbersome Web site to configure a system, you'll likely find an instant rebate offer or two to help minimize the cost. We'd also like to see Digital Storm refine both its online shopping experience and its system building technique. Given its competition from AVADirect, it's hard for us to recommend this exact 950Si configuration at this price, but we'd like to see more from Digital Storm, as it seems to be a competent system builder.

We've seen the 950Si's case in several other systems, perhaps most recently with Maingear's Ephex earlier in the year. Its size clearly suggests "powerful gaming computer," and it offers physical space inside to accommodate all the extra graphics cards, beefy power supplies, and liquid cooling tubes a hard-core PC gamer or performance enthusiast could want.

Digital Storm left our review unit's case glossy black, but its Web site offers a number of case customization options, including different paint jobs on the inside and outside, as well as on the screws, hose clamps, vents, and grills. Our one gripe with the design has to do with the always annoying side-panel fan and cathode lights, which require you to disconnect their respective power cables before you can remove the side panel itself. We realize the cooling benefits of the side fan, but either some kind of quick connect cable or a contact-based power connection would be much preferable to the wires currently in place.

The price-to-feature comparison between the Digital Storm system and its competition from AVADirect has some points of concern, although as we mentioned, an instant rebate offer on Digital Storm's Web site helps offset the damage somewhat. The two things that bother us chiefly are the fact that AVADirect achieved a higher overclocked setting with its Core i7 920 chip, and that Digital Storm included a dual-layer DVD burner and standard DVD drive, but no Blu-Ray drive. You can add a Blu-Ray reader for an extra $170, but AVADirect makes Digital Storm look cheap for not including one at this price.

We mentioned the overclocked CPUs, and, as promised, we've added an extra round of CPU stability testing to ensure that the overclocked systems we receive are stable enough to ship to a customer. Like the AVADirect system, the Digital Storm passed an overnight run of the Prime95 stress test. It also passed the LinX test, which was recommended to us by several readers. According to the two most common measures we know of, Digital Storm's overclocking is as stable as we can hope for.

Digital Storm advertises that it can clock the Core i7 920 chip to between 3.3GHz and 3.9GHz for $49, and to 4.0GHz or higher for $199. AVADirect promises free overclocking in the 10- to 20-percent range, and up to 50-percent gains for $100. That would only get the 2.66GHz Core i7 920 chip up to 4.0GHz at best from AVADirect, at the risk of paying twice as much for a lower boost from Digital Storm. Paying for overclocking is always a gamble, but Digital Storm offers both a better deal than AVADirect for a midrange overclock, and it's also willing to at least try for even more aggressive settings if you're willing to gamble $199.

We also realize that not all CPUs are equal, but it would have been nice, given its larger price tag, if Digital Storm had at least been able to match the AVADirect system on our performance benchmarks. Instead, as you might expect given its clock speed disadvantage, the Digital Storm system came in behind the AVADirect on every test. We're not talking about a major difference between the two, and it's only a matter of a few seconds on our media encoding benchmarks. But the fact is that the Digital Storm system was outperformed by a competitor that cost $700 less.

You'll see the same story on our gaming benchmarks, and we suspect AVADirect's overclocked GeForce GTX 295 is partly responsible. Both vendors charge $50 to overclock a dual-chip card like this one. On our tests Digital Storm comes close enough to the 60 frames-per-second hallowed ground on our most demanding Crysis 1,600 x 1,200 benchmark, so we'd have no hesitation connecting it to a 24-inch LCD. And again, it's not that far behind the AVADirect system, but it's disappointing that the Digital Storm system isn't faster given its higher price.

We found few surprises around the rest of the systems, but Digital Storm also ticked off all of the boxes we expect. The system comes with an HDMI video output by virtue of the graphics card, and you'll find an eSATA port for fast external storage among the other ports on the rear panel. There's no wireless networking, which we don't expect to find in a large gaming tower, but you get more USB 2.0 ports than you could want, along with optical and coaxial digital audio, FireWire, and 7.1 analog audio output. A media card reader on the front of the case accommodates removable storage from your portable devices, and if you rummage through the packaging you'll see that Digital Storm included all of the additional cables that came with the motherboard and the modular power supply.
