Will the Duo Core 2 E6700 CPU do 64 bit WinVista, or does one have to get a different CPU altogether, i.e., an Itanium? If his CPU will do it I may go toa 64 bit OS

Yes, though be careful as drivers for everything need to be digitally signed. Check that all of your hardware is supported before making the switch.Regards,Jim KarnNOTHING is foolproof to a sufficiently talented fool.

Thanks Jim for the quck reply. I just bought a new Velocity Micro with Windows Vista Ultimate, then without research or FOREthought put in another 4GB of ram on top of the 2GB in it. Then of course I found out WinVista will never use even 4GB of ram It does do 3.585GB LOL. May in the near future go ahead and go to the 64 bit OS, but I did know the drivers are iffy yet. Have to check my printer and scanner.PS. The Velocity Micro goes well above my wildest dreams with FSX.Thanks again

If you look on that performance page you will see an option to run a Vista benchmark/computer evaluation type application. After doing so my score jumped to 5.9, the highest, according to MS.Perhaps thats why your machine is not seeing all your ram?Worth a try, no?

Have you thought of Windows XP professional x64, it is a well developed 64 bit operating system and you can generally run 32 bit software on it aswell without any problems, the two snags being software that must access the operating system core must be 64 bit [ I presume Vista 64 has a similar issue with regard to software which accesses the core ] and that you need Windows XP Professional x64 drivers for your hardware. Because of the general instability problems of Vista as a new operating system, I would not go to Vista 64 or in fact any version of Vista untill, a service pack 1 is released.http://www.microsoft.com/windowsxp/64bit/default.mspxBest and Warm RegardsAdrian Wainer
