Here's an explanation of the differences between 32bit and 64bit, but
it's not specific to IE:
64bit apps might run /imperceptibly/ faster than 32bit apps (though,
in some circumstances, could run slightly slower), but the main
difference that the common user would be concerned with is 32bit code
is incapable of accessing more than 4GB of RAM /directly/. 64bit code
can access an almost unimaginable amount of RAM (4.2 billion times 4.2
billion bytes). Though, 2 individual 32bit apps can access two
separate chunks of 4.2GB of RAM at the same time, neither can access
more by themselves. With today's web apps, you're extremely unlikely
to see your browser get anywhere near 4.2GB of usage, and if you do,
it's probably because of a severe memory leak and you probably need to
kill the browser and restart.
In most cases, if you have a 64bit version of a program, use it. IE8
is a rare exception, because of the plugins. The plugin providers are
waaaaaay behind the times (even Microsoft's own plugins haven't gone
64bit yet with SilverLight, for an example). Just use the 32bit
version of IE8 until Adobe and the rest eventually come out with 64bit
versions. You're not really missing anything with the 32bit version.
FireFox is still 32bit as well. Would be nice if everyone finally
come on board with 64bit.
