More of clarification than a retraction Paul ;-) but point noted. Sounds like it won't be a problem once I've upgraded the RAM though.

Ooh, I need to retract this. Owen Taylor just posted some interesting actual
measurements with current F21 Workstation test images (which are Gnome
based). His conclusion is that with under 2GB of RAM, the memory saved by
using 32-bit is actually more of a big deal than the improvements you'd get
from the CPU in 64-bit mode.
See

for details and numbers.
This may be less true with LXDE or another more-lightweight desktop
environment, though.
