Does anyone know of performance of Revit 2012 on AMD Radeon HD 6000 series video card? I am specifically thinking of getting HD 6450 from Dell and our usage is primarily Revit MEP and AutoCAD MEP with rendering being done very, very rarely. The 6000 series isn't on Autodesk's list, and I am not sure this is due to the 6000 series being introduced fairly recently, or they somehow don't meet the standards. Dell doesn't offer anything other than Radeon HD 6000 on the decently priced Optiplex 790 series with i7 processor.
