I just found FreeMeter, and I thought I would pass it along. It's freeware that allows you to monitor up to 12 different things on your pc, while not impacting performance. It can monitor things like Disk Space Usage, Network Traffic, CPU Utilization, Disk Transfer Rates, Memory Usage, Running Processes, Page File Usage, System Uptime, System Resources and Network Ping. I personally have not used this software (yet), but it looked interesting and wanted to let others know of it's existence. After all, you can't beat the price.
