One liner to show a notification on Desktop in case the load exceeds 1.

load=`uptime|awk -F',' '{print $3}'|awk '{print $3}'`; if [[ $(echo "if ($load > 1.0) 1 else 0" | bc) -eq 1 ]]; then notify-send "Load $load";fi
I run this via crontab every one minute on my machine occasionally to see if a process is eating up my system's resources.

What Others Think

awk can do much more the '{print $3}' ... including substitution, math, and 'system' commands ... and your really not taking advantage of that. The above could be streamlined into: uptime|awk '{gsub(/\,/,"")}; {if ($8 > "1.00") system("echo Load:"" "$8)}' Note I only tested this with echo as I don't have notify-send ... but you should be able to modify it without issue.
