I wouldn't even attempt VR on a PC that old. If it's just for emulators, then an nVidia 730 GT is all I would toss into it. You can get a refurb for under $50 on newegg. I used one in my old HTPC for emulators and it did well with the exception of Dolphin playing F-Zero GX. But then, that's a pretty demanding game. other Wii titles worked ok but not great. But for MAME, ZSNES, NES, etc, etc.. it was a perfect card. Unless you are planning on playing anything more intense then that, don't waste your money on anything any more highend.
