A virtual machine doubles your memory need.  We tried running Linux and 
Windows using VM on our home server. It was easier and needed 1G less 
ram to run php, Apache and MySQL as native window versions along side on 
different IP or ports on  same  netcard and actual Windows OS, with IIS 
& MS-SQL which we need also.


I confess I only have two copies Eagle open a short while to cut & 
paste. I work normally with just one.  But even 1Tbyte RAM doesn't 
"need" a 64bit CPU. It's about architecture  and most 64Bit laptops can 
only address 3Gbyte for OS & Apps of 4G RAM.  32bit NT 4.0 enterprise 
can address more than 4G on suitable MBs and XP pro 32bit can actually 
easily address 2G per application and can use 3G.

A 64bit x64 Intel will use MORE RAM to run the same apps in 64bit 
versions too.

I had 512M from 2002 to 2009 in my laptop and then added 256M. I can't 
do schematics or programs any faster, nor any faster on 4G Core Duo  my 
son has.  His PC plays HD better and more modern games than my AMD64 
2400, but that's because of his rather expensive, much newer graphics 
card. x64 was started byt AMD marketing and adopted by intel as no-one 
loved their 64bit Itanium. In 1997 though there was 64bit NT4.0 for DEC 
Alpha64, it didn't sell well. Where is DEC now?
