Sure Ed, hope Jeff can find a problem - I wish the display were faster for large assemblies with lots of detail and blocks as well.
It’s possible the Quadro pro cards might be a better fit for your work than gaming cards, though. Here’s a link with some performance data in Rhino, getting a more expensive Quadro than the 2000 is pretty much throwing money away (at least until McNeel figures out how to better utilize high-end video cards, fingers crossed for V6): http://www.simplyrhino.co.uk/rhinotraining/pny_quadro_test.html
