Parts Research



  • More money doesn't necessarily mean more performace
    • Boards are made for specific purposes and excel at those specific purposes
    • Examples, can have multiple video card slots, wifi, 3.0 USB ports etc.
    • Get a product designed for your use case
  • Compatibility checks
    • DDR3 vs DDR4 memory sockets
    • RAM Frequency supported
    • Video cards supported
      • Brand Specific?
      • Supports multiple cards?
        • Nvidia 2 way SLI compatible
  • Sources


  • DDR4 will not fit in the same socket a DDR3 fits and vice versa (backwards incompatible)
  • DDR4 supports higher memory densities (up to 16 GB)
  • DDR4 supports higher frequencies
  • DDR4 has a lower voltage requirement and thus requires less power
  • DDR3 was out 7 years before release of DDR4 and DDR4 released in 2014
    • DDR5 expected in 2021 then? (5 years from now)
  • To better future proof should go with DDR4
  • Frequency a measure of how fast data can be accessed to and from the RAM
    • Higher frequencies better
    • Need to make sure compatible with mother board
  • Terms
    • DDR = Double Data Rate
  • Sources


Hard Drive

  • IDE Hard drive or SATA Hard drive or PATA Hard drive
    • IDE old style
  • RPM speeds determine how fast data can be read off the hard drive
    • Standard speeds are 5400, 7200 or 10000 RPM
    • Big bottle neck for computing
  • Hard drive cache also important quality
    • 8 mb to 64 megabytes
    • temporary quick memory
  • Numbers pulled from a 4 year old video

Video Card

  • Multi video cards?
  • Common brands of Graphics cards
    • NVIDIA
      • Separated from the pack in terms of gaming by the precense of PhysX
      • Has their foothold in a much broader market
      • 2GB weaker for multimonitor setups
    • AMD
      • 3GB better for multimonitor setups
    • EVGA
  • Comparing video cards by specifications is misleading because a lot of their differenceces come from the architecture (ie. two cards both having 4GB video memory can have vastly different performance)
    • Better method of comparing cards is to look at benchmarks on the games interested in
  • Common Terms/Specifications

Power Supply


  • Most common size 24" but 27" is the common larger screen
    • 24" good resolution 1080 x 1920
    • 27" good resolution 1440 x 2560
  • For a 4k monitor get a 30"+ sized monitor
    • If using 4k make sure monitor and graphics card support hdmi 2.0 connection or display port 1.2
  • Panels TN vs IPS
    • TN: + cheap, + response times, - viewing angles, - color accuracy
    • IPS: + color accuracy, + viewing angles, - expensive, - response times, - IPS glow
  • Any refresh rate > 120 Hz you'll struggle to notice the difference
  • G-Sync is good but can only be used with an nvidia graphics card
