Your old computer uses much more energy than a new one. Powering the
beast creates much more CO2 than the new ones ...
But about half the energy used by a PC is in its manufacture and
delivery (called "embedded energy") and half the electricity to run it.
So the new computer has to save a lot of energy to make up for its
manufacture. If the components are reused or recycled, rather than
thrown away, this will lower the energy use. Also newer computers tend
to have less materials and so take less energy to make:

My students spend a semester working out the trade-offs between
a new computer using less energy and the waste caused by replacing the
old computer: http://www.tomw.net.au/ict_sustainability/introduction.shtml
binning it (hopefully decently) ...
Yes, Australian has a "National Television and Computer Recycling
Scheme", funded by industry. Old equipment is sorted, packed into
shipping containers and then sent for recycling:
