Doug regarding "...am wondering if this
change of spec entitles me to download and purchase the OEM 64bit
version...." - Simple answer "no". technically there ae no OEM versions to
purchase via download - "OEM version"is applied to software installed by the
manufacturer.
Your computer must be 64 bit capable - processor, chipset and so forth
otherwise the OS will not install - also it must be a clean install not an
upgrade.
Regarding 32 bit RAM - lots of opinions about 2 gig versus 4 gig. Video and
audio drivers are loaded in the bottom half of the memory stack -(one of the
application limitations in addtition to addressing that limits 32 bit to 4
gig). If you are a heavy graphics and audio "usere" 4 gigs is a definite
assest.
In addition , most users have Vista set to manage virtual memory - Vista
sets virtual memory size based on RAM - 2 gig RAM and virtual memory about
3.5 gigs - 4 gigs RAM memory 6 gigs. Virtual memory, Superfetch and
ReadyBoost work in concert- draw your own conclusions.
