So the simplest solution is to try newer and older Quadro K2000 graphics drivers to find one that works. As I mentioned before the Nvidia Quadro cards are a niche market and so my experience has been that the graphics drivers are less reliable than than the video game oriented Nvidia GeForce cards which have a huge market. There is no telling which specific graphics cards will be afflicted by graphics driver bugs. When getting a new card I would choose a widely used and current generation card that is within your budget. If you want to use stereoscopic shutter glasses that will limit the choice, probably requiring a niche card like the Quadro series. You can get some idea of the performance of various graphics cards on benchmark sites, for example</div><div class=""><br class=""></div><div class=""><span class="Apple-tab-span" style="white-space:pre"> </span><a href="http://www.videocardbenchmark.net" class="">http://www.videocardbenchmark.net</a></div><div class=""><br class=""></div><div class="">There are Chimera specific benchmarks here</div><div class=""><br class=""></div><div class=""><span class="Apple-tab-span" style="white-space:pre"> </span><a href="http://plato.cgl.ucsf.edu/trac/chimera/wiki/benchmarks" class="">http://plato.cgl.ucsf.edu/trac/chimera/wiki/benchmarks</a></div><div class=""><br class=""></div><div class="">There are entries for Quadro K2000 so people have found working graphics drivers — the table even says what driver they were using.</div><div class=""><br class=""></div><div class=""> For a specific recommendation, if you want a current popular very high end card, an Nvidia Geforce GTX 1080 for about $600-$800.
