I have a Mac Quadra 950, and I was looking at PowerPC upgrade options. What card is compatible with it?

There is some information about it here.

For example, I have an Apple PPC Upgrade card 66 Mhz, and it works great. This allows you to run Mac OS 8.5 - Mac OS 8.6 on Quadra 950, but I didn't like how it works, too slow memory for these systems. But as an experiment - why not? :)

That's great for letting me know. Is that the only speed (66MHz) that works on a quadra 950, or can I use others?

If you manage to find DayStar at 100 Mhz, it will be 100 Mhz.
Recently at an auction in Japan, I saw an 80 Mhz with memory banks, I also participated in it, but the final price was higher than I could have paid that day.

Back in the day, I was the owner of a Quadra 950. I wanted to upgrade to PPC so I swapped the motherboard to the WGS 9150. I am not sure in this day and age if that would available and if it is, how expensive it would be

Thank you everyone for your input. I think I'll stay with the CPU I'm using, they're too expensive.

Realistically, it makes a decent 68K Mac into a poor Power Mac. I didn't find the value proposition for them all that compelling even when they were cheaper. I have one for my Q800 which I almost never use because it won't work with A/UX, which is what that machine usually runs - and I have plenty of Power Macs here.
