This will depend broadly on the level of quality that you desire.
There are eight settings for bitrate/quality which will affect the
upstream needed (total of the audio and video bitrates, plus a little
overhead).  These profiles are taken from the Apple specifications for
optimal bitrates and resolutions for their devices, and represent a
sampling of those recommended for both cellular and wifi networks.
They are:

224p:
110 Kb/s Video, 64 Kb/s Audio, 224 Height

224p HBR:
400 Kb/s Video, 64 Kb/s Audio, 224 Height

360p:
600 Kb/s Video, 64 Kb/s Audio, 360 Height

360p HBR:
1200 Kb/s Video, 64 Kb/s Audio, 360 Height

540p:
1500 Kb/s Video, 64 Kb/s Audio, 540 Height

540p HBR:
2200 Kb/s Video, 64 Kb/s Audio, 540 Height

720p:
2500 Kb/s Video, 64 Kb/s Audio, 720 Height

720p HBR:
4500 Kb/s Video, 64 Kb/s Audio, 720 Height

My Core 2 Quad Q6600 (about 3 years old now) keeps up with the 540p
baseline profile while also delivering what I consider pretty nice
quality.  540p is the default profile on the iPad, though you can set
any you like.  224p is the default setting on iPhone/iPod.  As the
variables for each individual user will vary quite a lot, you will
need to find the sweet spot for your own configuration.

Unless you have an Atom backend, in which case, the sweet spot is down
the street at your local computer retailer, where they will be happy
to sell you a computer more suited to this particular task :)
