No, why would you say that? Smilie I bought the components for the computer at MicroCenter and assembled it myself. I haven't been to a BestBuy for ages.

I can't tell how you intended the statement since your intonation doesn't come through the text. Are you doubting my statement on 64-bit addressing? My understanding is that AMD64 systems set 16 memory bits (actually I think 16 of the middle bits, rather than just the 16 upper bits) to 1, limiting the actual space that can be accessed to 2^(64-16) = 2^48 = 64 terabytes. Let me try to Google up a source,

OK, I have one:
EmbeddedDeveloper.com - x86 - AMD64 (64-bit)
Actually this gives a limit of 48 bits of virtually-addressed memory and only 40 bits (1 terabyte) of physical memory.

Of course these are all better than Vista's 37 bits (128 GB for Vista Business), though I think that's an artificial restriction.
