SETIWatch (previously named SETIView) displays the CPU time, percentage completed, strongest peak and strongest gaussian. It does this by polling SETI@home program in 1 to 300 second intervals. This program can be used for the CLI or the GUI Windows clients and is very useful for monitoring multiple workstations. Make sure you get SETIlog, another great utility from the author of SETIwatch. SETIlog allows you to track completed WU's.
SETISpy is another great utility for WU tracking (it also shows cpu speed & type)
