the mobo may be overclocked. Without an exact motherboard model #, it is hard to tell what can go in your system.

PIII have Intel speed gizmo to reduce the power down to save battery. You can disable that in the BIOS and make the CPU run at full speed. So you have 1.7GHz that's quick! Some PIII have removable CPU where you can upgrade the mobile CPU. If you got 1GB of RAM and the HDD is spinning at 7,200RPMs you can install Windows 7 Ultimate and get away it on PIII.
