I wonder how will run autocad 2010 in windows vista 64 beat...I having problem with XP..I need more memory..I have 4 GB....it frozen when I do rendering....this will be better with windows vista 64 beat and having 8GB of memory......

AutoCAD 2010 is fully supported in Vista 64. You will have access to all of your 4GB or 8GB of RAM.

Yeah definetly. Vista 64 w/8gb ram and autodesk 2010 is what I run and so far crashes less the XP did.
