3.5 stars Very good

The Good New high-end Athlon 64 chip supports unbuffered memory; application performance rivals the fastest Intel-based systems'; handy media-card slots on optical drive; fast hard drives; generous standard warranty.

The Bad Aging graphics card; anemic online support; annoying Polywell sticker on front panel.

The Bottom Line With AMD's new 939-pin Athlon 64 FX-53 processor, the Poly 939VF-FX53 boasts leading desktop performance, but gamers will want to opt for a more current graphics card.

The Polywell Poly 939VF-FX53 looks no different from many of the other Polywell systems that have passed through CNET Labs. The boxy, aluminum midtower case lacks any sort of geek chic--the only adornment is a cheesy Polywell sticker plastered just below the power button on the front panel. Inside this ho-hum-looking system, however, resides the very latest desktop technology from AMD. Gamers will want a system with a more recent graphics card, if you're a digital-content creator or another sort of power user, the Polywell Poly 939VF-FX53's bleeding-edge desktop performance will do the trick.

The $2,549 Polywell Poly 939VF-FX53 gave us our first glimpse at one of the new 64-bit AMD chips: the high-end Athlon 64 FX-53. If you think that name looks familiar, you're right: it's the same as AMD's last-generation performance chip. In fact, the two chips run at the same 2.4GHz speed, share the same 1MB amount of L2 cache, and are built on the 0.13-micron process. The differences in the chips are few: the new FX-53 chip has 939 pins to its predecessor's 940, and it supports the use of unbuffered memory.

Buffered (or registered) memory is primarily used in servers where reliability is more of a concern than raw performance. Buffered memory improves reliability of high-speed data access but slows down performance. The older 940-pin FX-53 was basically a renamed AMD Opteron server processor aimed at desktops. With the 939-pin FX-53, you get a more consumer-friendly CPU that allows you to use faster and cheaper unbuffered memory. More power for less dough is music to any desktop buyer's ears.

Our Poly 939VF-FX53 test system in particular uses 1GB of unbuffered DDR400 SDRAM--standard issue for almost all performance PCs these days. Both CPU and memory sit on an MSI 6702E motherboard with Via's K8T880 Pro chipset. As you can see on the charts below, the Poly 939VF-FX53's application performance is on a par with that of systems running Intel's current speed leader, the 3.4GHz Pentium 4 Extreme Edition chip. It also edged by 5 percent the Velocity Micro Vision FX AVD , which uses the older 940-pin Athlon 64 FX-53 chip. Of course, this performance difference could come from the Poly 939VF-FX53's two 10,000rpm Western Digital hard drives (in a RAID 0 configuration), which offered better performance than the Vision FX AVD's two 7,200rpm drives.

The Poly 939VF-FX53's 3D graphics scores are less impressive. Using an older Nvidia card, the GeForce FX 5900XT, our test system turned in a substandard 47.7 frames per second on our high-end 1,600x1,200 Unreal Tournament 2003 test. Gamers will surely see improved frame rates with a more current graphics card, such as the GeForce 6800 Ultra or ATI Radeon X800 .

As configured, our Polywell Poly 939VF-FX53 test system is better suited for high-end graphics tasks other than 3D gaming--digital content creation and DV editing, for example. The system's two optical drives, a multiformat 8X DVD-RW drive and a DVD-ROM drive with media-card slots, give you flexibility with burning chores, and the aforementioned 10,000rpm hard drives give you quick access to your data.

Polywell backs the Poly 939VF-FX53 with a generous three-year-parts, five-year-labor warranty that includes one year of toll-free, 24/7 phone support. Keep Polywell's number handy, though, because the user manual is just a generic system manual and online support offers little help.

To measure application performance, CNET Labs uses BAPCo's SysMark2004, an industry-standard benchmark. Using off-the-shelf applications, SysMark measures a desktop's performance using office-productivity applications (such as Microsoft Office and McAfee VirusScan) and Internet-content-creation applications (such as Adobe Photoshop and Macromedia Dreamweaver).

To measure 3D gaming performance, CNET Labs uses Epic Games' Unreal Tournament 2003, widely used as an industry-standard benchmark. We use Unreal to measure a desktop's performance with the DirectX 8.0 (DX8) interface at a 32-bit color depth and at a resolution of 1,024x768 and 1,600x1,200. Antialiasing and anisotropic filtering are disabled during our 10x7 tests, and are set to 4X and 8X respectively during our 16x12 tests. At this color depth and these resolutions, Unreal is an excellent way to compare the performance of low-end to high-end graphics subsystems. We report the results of Unreal's Flyby-Antalus test in frames per second (fps).
