  4. Low End: EMACHINES desktop for $460 Processor & Memory: • AMD Athlon II 170u 2.0 GHz • 4GB DDR3 SDRAM memory Drives: • 500GB (7,200RPM) SATA 3Gb/s hard drive • 16x SuperMulti DVD R/RW drive Graphics & Video: • 18.5" diagonal widescreen flat panel monitor with integrated speakers • Integrated Graphics NVIDIA GeForce 6150 Communications: • 9 USB ports, two PS/2, one VGA • Gigabit Ethernet • Multi-in-One memory card reader Keyboard & Mouse: • PS/2 Keyboard  • Optical Mouse  Operating System: • Microsoft® Windows 7 Home Premium(64-bit) Additional : • Microsoft Office Starter • Power Supply: 300W

  5. High End Systems • More memory • A larger hard drive (RAID system) • A faster processor • A graphics card with a large amount of memory • A Blu-Ray drive • Touch screen • Windows 7 Ultimate

  6. Notebook Computers • Notebook prices are always higher than desktop for similar power. • Use processors that conserve power. • Price varies based on: • Processor • Screen size (diagonal) • Amount of memory • Hard drive size

  7. High End Processors Two companies compete: AMD and Intel Intel’s top of the line processor is the I7 4 cores runs at 3.06 GHz up to 12 MB of Cache 8 channels of hyperthreading AMD has the Phenom II X6 6 cores runs at 3.2 GHz 6 MB of cache

  8. Notebook Processors Netbooks and laptop computers need to conserve power. AMD and Intel make less powerful, ultra low power processors AMD Neo: 2 cores, 2MB cache, 1.7 GHz Intel Atom: 1 or 2 cores, .5MB cache, 1.83 GHz

  9. Medium Range Processors AMD family includes: Phenom Triple Core Turion Dual Core Athlon Dual core. Intel family includes: I5 I3 Pentium Dual core.

  10. Protect your investment • Surge Suppressor – absorbs power surges or spikes • Anti-Static Mat – if floor is carpeting, you can build up static electricity in your body by walking to the computer • UPS – battery powered backup in case of a power failure • Anti-Virus software – protects computer against malicious software that will delete files or use your computer to infect others. • Backups – Have CD’s, DVD’s or USB drives that you back up your important files to regularly
