Pdesopo, Why don't you try 64-bit Windows Server 2008? It's the server equivalent of Vista but has all the desktop stuff turned off, including Aero so it's lean and mean. You can also optimize it for running as a workstation rather than a server. See www.win2008workstation.com . Most Vista 64 drivers have no problem running under Server 2008 x64. Moreover, you can download Server 2008 effectively as an 8 month trial from Microsoft. hope this helps
