i run 3 monitors side-by-side at 1152x864... base level comcast
cable... i think 3mbit down / 384kbit up (i'm not 100% sure)
It's decent for me... I can be writing these e-mails on one monitor,
running etka and my japanese parts cd on another monitor and then
surfing the web on the third.
The internet speed slows down considerably when my parents are home
however, since the router makes port 80 more important, bandwidth
wise.
