If you're making the switch from 98 to Vista, you definitely want an entirely new machine. The requirements for Windows 98 were: * 66 MHz processor * 16 MB RAM * 500 MB hard drive space The requirements* for Windows Vista are: * 1 GHz processor * 512 MB RAM * 20 GB hard drive space * video card with 32 MB RAM on-board * Note that these "minimum requirements" will be barely able to run Vista. A system with a 3 GHz processor and at least 1 GB RAM are usually listed as minimum values by non-Microsoft parties. It is unlikely that the motherboard that came with your Windows 98 computer will be compatible with the minimum requirements for Windows Vista.
