Another note: The page linked to below, namely http://www.emachines.com/products/products.html?prod=eMachines_T3256 Is for a PC with an Athlon XP processor, which, I'm pretty sure, is 32-it. Another bit of confusion might come from the so-called "AMD Athlon 64". If I'm not mistaken, this is a 32-bit CPU that supports AMD's instruction set for 64-bit applications. So, for example, you could run 64-bit (and 32-bit) Mathematica on it, but it would be slower than on an Opteron, which is AMD's REAL 64-bit CPU. I've been shopping around a little , and this this the settup I currently favor (but with more RAM!): http://www.micronux.com/catalog/product.php?products_id=168 Properly configured, this would be about $1,500.

WRI advertise Mathematica 5 for AMD64, see: http://www.wolfram.com/news/amd64.html. I presume that this is the "Linux (64 bit optimized) " version . They have checked compatibility with SUSE Linux Enterprise Server 8 which supports 64 bit technology, hopefully this means that its OK on SUSE's desktop version; see http://www.suse.com/us/private/products/suse_linux/prof/64bit.html. So it looks as though a cheap 64 bit Mathematica is possible. Has anybody done it?
