This desktop is powered by the 2.2 GHz AMD Athlon 64 X2 4200+ dual-core processor, which increases the efficiency and speed of the PC while running multiple programs and the latest multi-threaded software. Store more music, videos, and data on the roomy 250 GB Serial ATA hard drive, which offers fast transfer rates. It also comes loaded with 1 GB of RAM (which can be bumped up to a very generous 8 GB), an integrated Nvidia GeForce 6150 video/graphics card with 128 MB of dedicated video RAM, a wide variety of connection ports on both the front and rear of the box, and a 15-in-1 memory card reader that's compatible with today's most popular digital camera formats.

It comes preinstalled with Microsoft Windows Vista Home Premium, which includes all of the Windows Media Center capabilities for turning your PC into an all-in-one home entertainment center. In addition to easily playing your DVD movies and managing your digital audio library, you'll be able to record and watch your favorite TV shows (even HDTV). Vista also integrates new search tools throughout the operating system, includes new parental control features, and offers new tools that can warn you of impending hardware failures.

The Basics

• Processor: AMD's Athlon 64 X2 4200+ dual-core processor is built for tomorrow's 64-bit applications, which will require a processor with significant power. It outperforms the highest-performing AMD Athlon 64 4000+ single-core processor on multi-tasking benchmarks by up to 30 percent. Dual-core technology is like having two processors working together, each one taking care of different applications, so power-users actually experience greater performance when multiple applications are running. Digital media enthusiasts will appreciate the enhancements while simultaneously working in high-definition video and photo editing and audio mixing programs. It includes such AMD features as HyperTransport Technology (which increases the communication between integrated circuits) and Enhanced Virus Protection.

  This 2.2 GHz processor offers a system bus with speeds up to a blazing 2000 MHz and each core offers a 512 KB L2 cache--for a 1 MB total. (An L2, or secondary, cache temporarily stores data; and a larger L2 cache can help speed up your system's performance. The FSB carries data between the CPU and RAM, and a faster front-side bus will deliver better overall performance.)

• Hard Drive: The extra-large 250 GB Serial ATA (SATA) hard drive (7200 RPM) offers a wealth of storage space, perfect for storing a vast multimedia collection or for editing digital video. This SATA hard drive also quickens the pace with a higher speed transfer of data--akin to FireWire and USB 2.0.

• Memory: The 1 GB of installed RAM (PC4200, 2 x 512 MB, 533 MHz) is a fine start, but you'll want to add more RAM to handle today's demanding multimedia and gaming software. This desktop has a 8 GB maximum RAM capacity (8 x 1 GB), perfect for high-def video and 3-D gaming.

• DVD/CD Drive: This multiformat DVD/CD drive is compatible with writing both DVD+ and DVD- disc formats as well as dual-layer (DL) DVD+/-R discs, which can store up to 8.5 GB of data. It features 4x DVD-R DL Write Once, 8x DVD+R DL Write Once, 16x DVD+R, 8x DVD+RW, 16x DVD-R, 6x DVD-RW, 5x DVD-RAM, 40x CD-R, 32x CD-RW write speeds and 40x CD-ROM, and 16x DVD-ROM read speeds.

  This LightScribe DVD+/-RW drive lets you laser-etch silkscreen quality text and images on to CDs and DVDs . Your software, PC and discs work together for a no-hassle way to burn just the labels you want. After you burn content, just flip the disc over, reinsert and burn your label--anything from a simple title to a full-disc work of art.

• Keyboard & Mouse: It comes with an HP multimedia keyboard and scroller mouse (both with PS/2 connections).
