Why the fsck would you buy one for your PC in the first place: it's an accelerator for Macs, You know, the computers made by Apple. What did you think PCI bus was exclusive to Wintels or something?
Emulation has NOTHING to do with real hardware, it's a purely software based means of 'tricking' the program you want to run into thinking that your hardware is actually the native hardware of the program. Thus UAE virtually recreates a 68k Amiga in every detail down to the custom chipset.
Likewise an emulator could be designed to virtualise a standard PPC based PC (which is what Neo-Amigas are) but that would again be entirely a software based means of 'fooling' the programs you want to run (in this case games) and the speed of the emulation will as with UAE depend entirely on the specs of your PC, not an old Mac accelerator card.
