Hi I work for a K12 school system on a limited budget. Lab teacher told me that it took them about an hour to render a Solidwork project. We are still running Dell 780 Optiplexes using the built in HD Intel graphics, Intel Core2 Duo processor, 8 gigs of ram with Windows 64 bit OS. My boss informed me that we don't have a budget for a new lab, but he would consider upgrading it.   I'm thinking of putting an SSD hard drive. Would that be enough?  I'm just writing to see what would be a budget video card that you would recommend for the Solidworks program (2016,2017,2018). Thanks
