Needing a Favor / Help (VooDoo5 Utility !!!!)

[Mindf!3ldzX]

Sup, im at my brother in law's crib and working on his PC.
His gaming/entertainment PC rig is :

Pentium - III 600MHZ
Memory - (100mhdz or 133mhz)
Video Card - VooDoo5 5500 3DFX 64MB PCI (Two 3D Chips )
HD - Plenty Space
Operating System - Windows XP (sp1 only) This is going to be changing.

This system run's OpenGL horridly, D3D isnt much better , I *know* this there is a way to Beef up the OpenGL & D3D with some overclocking ,but I cant find NO working DL's for any VooDoo5 5500 PCI specific or "Supported amongst Others" Overclocking Applications for this Video Card,and I cant find any NORMAL App.Utilities for this Video Card.
Any help is appreciated , besides telling me to rAWK-SUM-3DFx because that's like forcing me into the DarkAge's , VS Tweaking the Video Card's TWO3D Accelerator's itself & the Memory a little bit.both 3DAcc. Chips have heatsinks & fan's,and I checked the cards "temperature by backside of fingers"(ghetto method yes) after a hour of N64 Emulation,and its running pretty damn cool compared to the various ATi / nVidia cards I have owned/own.(GF2MXprior,Radeon7000prior,Radeon92000current lyowned)
