Please bear with me because I am NOT highly technical. I don't actually know what 32-bit vs. 64-bit means, BUT:
I know Vista Ultimate comes in 2 flavors (32- and 64-bit)
I just saw on my receipt that the laptop I ordered is coming installed with "MSWIN VISTA ULTIMATE 32."
Separately, I ordered a 2GB stick of RAM from Newegg to bring the total to 3GB, but I recall reading elsewhere that 64-bit is desired if you have a lot of RAM.
Is this correct? What can I do about it (as close to plain english as possible please!)?
