    3. 3. Processors and RAM <ul><li>Can I not just buy a faster processor and put it in my machine? </li></ul><ul><li>Processors must use the same type of slot (slot 7, slot 1, slot A, for example) as the motherboard </li></ul>
    4. 4. Processor Upgrade Compatibility <ul><li>The motherboard and BIOS must be compatible with the new processor </li></ul><ul><li>The motherboard must be able to adjust to the new processor’s electrical requirements </li></ul><ul><ul><li>switches may need to be changed on the motherboard </li></ul></ul>
    5. 5. Finally... <ul><li>RAM must be compatible with the CPU </li></ul><ul><li>The computer or motherboard manufacturer has the information that you will require </li></ul><ul><li>Check the manufacturer’s Web site for compatibility </li></ul><ul><li>You can upgrade the CPU and RAM at the same time </li></ul>
    6. 6. <ul><li>Is it cheaper to buy a new system than upgrade components? </li></ul><ul><ul><li>Rule 1: Never upgrade or buy a new system during times that you absolutely need your computer </li></ul></ul><ul><ul><li>Rule 2: There is no easy answer. Always calculate costs </li></ul></ul><ul><ul><li>Rule 3: Plan on upgrades taking about three times longer than planned, if you do not do these often </li></ul></ul>
    7. 7. Do I Need That Speed? <ul><li>In general, processor speeds have outpaced business applications </li></ul><ul><li>If you work on graphics, you will need a fast processor </li></ul><ul><li>If you are a gamer, you may also need fast processor </li></ul>
    8. 8. Main Memory <ul><li>Increasing RAM? Older Intel chips may not process well as memory exceeds 64 MG </li></ul><ul><li>Motherboards with VIA and other chipsets do not have this problem </li></ul>
    9. 9. Focus on PC Purchasing <ul><li>Research online evaluations of PCs performance, manufacturing support, and capabilities </li></ul><ul><li>http://www.pcworld.com </li></ul><ul><li>http://www.pccomputing.com </li></ul><ul><li>http://www.cnet.com </li></ul><ul><li>http://www.zdnet.com </li></ul><ul><li>http://www.pcmagazine.com </li></ul><ul><li>http://www.windowsmag.com </li></ul>

    11. 11. Motherboard <ul><li>Review motherboard capabilities before purchasing a system </li></ul><ul><li>Call the manufacturer if the information is not readily available </li></ul><ul><ul><li>this will affect future upgrading </li></ul></ul><ul><ul><li>http://www.tomshardware.com </li></ul></ul>
    12. 12. Microprocessor <ul><li>Intel and AMD are battling out processor bragging rights at both the low and high end of CPUs </li></ul><ul><li>Determine limitations and differences before purchasing </li></ul>
    13. 13. Compatibility <ul><li>Most software is backward compatible with new chips </li></ul><ul><li>The older the hardware, the less likely that it will install easily and function completely in new systems </li></ul>
