    To expand on Tom's advice, to figure out what your lab should have
    in it, you should collect examples of the kind of data you want to
    look at and test it on the computer configuration you're
    considering.  It could be that the graphics is fine, but the CPU is
    too slow.  But as Tom said, for much data, a current Intel
    CPU/graphics combination is adequate.  Many AMD CPU/graphics
    combinations would be adequate too -- generally, for the same price,
    an AMD system will have better graphics and a slower CPU than an
    Intel system, so depending on the data, that can be a good
    tradeoff.  Tom's Hardware has an Intel &amp; AMD Processor
    Hierarchy, <a
      href="http://www.tomshardware.com/reviews/cpu-hierarchy,4312.html"><a class="moz-txt-link-freetext" href="http://www.tomshardware.com/reviews/cpu-hierarchy,4312.html">http://www.tomshardware.com/reviews/cpu-hierarchy,4312.html</a></a>
    that should help.  Historically, AMD's graphics driver has been
    better than Intel's, which is another issue to consider.<br>
    <br>
    To get an idea of what you'd need for larger system, look at the
    Chimera benchmarks at <a

    (need more results, so everyone please run the benchmark on your
    setup), and check Tom's Hardware's <span class="title font spaceB5
      db nolinks">Desktop GPU Performance Hierarchy Table, <a
        href="http://www.tomshardware.com/reviews/gpu-hierarchy,4388.html"><a class="moz-txt-link-freetext" href="http://www.tomshardware.com/reviews/gpu-hierarchy,4388.html">http://www.tomshardware.com/reviews/gpu-hierarchy,4388.html</a></a></span>
    to see where various graphics cards rank.<br>

      Hi Fabian,
      <div class=""><br class="">

      <div class="">  Intel graphics built into most computers is
        adequate for most uses of Chimera.  If you want to manipulate
        molecules with a hundred thousand atoms or large density maps
        (512 ** 3 or larger) the rendering will be smoother with any
        consumer video game playing graphics card from nvidia or amd.
         Usually such large systems are not used in tutorials that would
        be presented in teaching lab.  The most common trouble with
        graphics and Chimera is caused by old graphics drivers (&gt; 3
        years old).  Update to date graphics drivers for laptops are
        often not available.</div>
