CAD: AutoCAD 2013 And Inventor 2013
The differences between cards are marginal. At this point, as long as you’re dealing with 2D output, the type of card you’re using doesn’t really matter. From workstation- to gaming-class hardware, all of these cards are sufficient.
There are clearer reasons to favor one board over another if you isolate 3D performance. Desktop-oriented cards do benefit from DirectX support. However, the new Radeon cards aren’t stunners by any stretch; they roughly achieve similar results as their genetic predecessors.
Autodesk Inventor 2013
Inventor also employs DirectX, which means that even gaming boards stand a chance. Interestingly, the Radeon cards fare better than they did in AutoCAD.
