I've recently bought a new Acer Aspire desktop PC which came preinstalled with Vista Home Premium 32bit but I have a Windows Server running at home which I use to manage my home network through a Windows Domain Controller, Vista Home Premium obviously won't allow me to connect to a Domain Controller, so I also purchased a retail upgrade of Vista Ultimate.
My question is this, is there a way to tell if my new Acer PC is capable of running the Vista Ultimate 64bit version. The reason I ask is because everything I've read since I bought my new PC indicates that the 64bit addition of Vista would be more appropriate for the tasks I perform regularly with my PC - Acer haven't been much use to be honest, I did email their support desk and the response I got was that they couldn't tell me if it's capable of running 64bit editions as it has not been tested with it.
From everything I've read about 64bit Windows so far, it seems to suggest that a PC running 3GB or less of RAM is more suited to 32bit while anything above that is more geared towards 64bit, my Acer PC came from new with 4GB RAM which leads to be think it may be capable of running the 64bit edition. Also as I understand it, and correct me if I'm wrong, but it depends almost entirely on the processor installed in the PC if it can run the 64bit version. My PC came with an AMD Phenom 9550 Quad-Core 2.2GHz Processor but I can't even find a matching model processor listed on AMD's website to know if it will run the 64bit version or not.
Can anyone suggest a way to check of my PC is capable of running the 64bit edition without physically attempting to install it from the DVD, are there any applications available for download or anything I can check through my current installation that might give me a clue?
I greatly appreciate any help, pointers or suggestions.
