Bought a rare version of the PowerVR PCX1

Whats the perf gain look like between a p3 1GHz and a p4 3GHz? Surely it’s minimal?
I'd say something between 5% and 10%.
I personally dislike using it in a much newer system, but if you want to get the most out of it, it will be slightly faster that way.
Make sure to not use a S3 or SiS primary card, it's slow with a PowerVR.
Finally, I made a PCI bus speed comparison with an overclocked PCX2 (90MHz).
Quake I :
29MHz : 34.1
39MHz : 34.6
System is a 440BX board with a Celeron Tualatin 1300.
The primary card is an ATi Rage 128 Pro (AGP).
PCI bus speed relevance is clearly overated, even with a 90MHz card. At least on a 440BX motherboard.
As a bonus, here is Tomb Raider 5 runing on a PCX2 @90MHz . I know it was an old engine when it came out in 2000, but I found satisfying to play a 2000 game smoothly with a PCX2.
Sorry for the dark image.
