There are lists of new hardware compatible with Win98, including chipset (mostly intel), video cards,... In fact, Nvidia had full support up through the 8 series. Why bother? Why bother with half of the things geeks do? Why bother connecting a record player to a PC? Why bother making a 5.25 floppy work, why bother attempting to install Windows 3.11?
ITS FUN. or in his case, who knows.
