My mate who uses BigPond Cable can get high 5's to DSLReports speed test and that's from Sydney to Los Angeles. He can also download my script in about a second (1.4MB). The top speed would simply depend on what the ISP will allow and what traffic you are sharing the pipe with. The only thing I don't like about cable is that because it is a shared resource the usage of others in the same street can play havoc with consistency whereas with ADSL you are the only user back to the exchange, hence the slightly higher price.
