Solidworks Video Cards Refresh Rate

I now have a 27" monitor and found that when set to 1280x720, 1600x900, or 1920x1080, a Nvidia Quadro FX3800 video card will not refresh at a rate faster than 60hz.  A new video card was in the plans anyway so I'm wondering what video cards others would recommend for SolidWorks 2013 that can also get 70hz or better refresh rates on a 27" monitor?  I don't need a high end card and would rarely have an assembly open with more than 20 components on a Win7 64bit workstation.
