How To Determine if Your Computer Is 32-Bit or 64-Bit
Bad choice of terminology on the author's part. He's equating "Computer" to "OS." He's a Java programmer, so you can't expect much more. Of course you're confusing "Computer" with "CPU," but you get a pass because you could claim by "Computer," you're including the chipset/BIOS.
Look, you don't have to take my word for it. Intel says it's a 64-bit chip, and I know they're correct because I'm running Win7 x64 on a Core 2 Duo.
One of two things is happening here. Either you were lying about the CPU, or you want to be convinced it's not 64-bit. I'm not sure why you'd lie about the CPU, so I'm going with the latter. In which case, I understand. You want a new computer, but you can't justify the purchase unless you can prove it's "worthless" by not addressing 2TB of RAM. Just go for it and get a new one; it's obviously what you want, and you can still use the old one. Just load a bunch of hard drives in it, load one of the free NAS OSes on it, and you have yourself a file server at the cost of a few hard drives.
