I don't believe that any of the front-ends have any ability to monitor system information like that.
Motherboard Monitor does, and it's great. It will also inform you of memory utilization, CPU usage, HDD usage, fan speeds, etc. I'd check to make certain it's compatible with your motherboard, though.
In my project (if/when I can ever afford to get it off the ground!), I plan on having an character LCD display that shows computer information, including temps, CPU usage, time, all through a software called LCDC. Very very slick stuff.
