We currently have some workstations with ATI Raedon HD 4550's and are looking to upgrade. We are getting SolidWorks but our CR's don't require us to use 3D models as we build machines not make parts. We are looking to start putting the machines into 3D models for our future reference, so we are basically intro to 3D CAD. What graphics cards would you recommend as this won't be a daily thing for us. We could get nVidia 460 fermis or ATI 5770's for under $200 but how would those compare to spending $400-500 for the ATI 6970's or nVidia 580 or something around those?
Just need some direction as how much better the higher end cards are and if they are worthwhile. Also, newegg has "Professional" cards but they don't look better than the cards mentioned above, thoughts?
