That card has 32MB video memory, and thus it wouldn't be much of a upgrade.

The 7500 was the only card listed to work with the 466 mhz model. If you have used the other models on this model PowerMac, and it worked, great! I've found some of the older PowerMacs can be picky about video cards.
The 7500 is double video memory and supports Quartz Extreme which was implemented in OSX 10.2. Quartz Extreme isn't available on his current card so the 7500 would be an improvement.
