I'm glad it works for you. I maintain that there are some sites and some
plugins that won't work correctly on amd64, while they work fine on x86.
Last time I tried virtualbox, would not start that proprietary OS on

Are you sure, that the x86 tests were carried out with the amd64-kernel
for x86? I am sure that 686-kernels will be outperformed by
amd64-kernels. My golden compromise between performance and usability is
a amd64 kernel with 32-bit userland.
If it's really the amd64-kernel on x86 that's outperformed, I'd start to

After the recent change of German copyright (Urheberrecht), libraries
started to send copy-protected pdf's that require a closed source
DRM-plugin, which is only available for i386. So, what you gain in speed
by improved number-crunching, might be lost by not being able to study
the scientific literature :-(
[Of course, I would prefer to read the literature without the need of
non-free software! ]
