+4 Culture (from Monument, Ampitheatre, Opera House, Museum), 50% per pop,+2 Culture and +4 Tourism from 2 Great Works and +3C and +4T from Museum's Theming. Only 32 Pop needed. And you'll be missing 4T and 3C that the Uffizi's GArtitst provides.
I never considered that Aesthetics' Finisher could affect nonTourism bonuses.
First of all, I'm going to go ahead and say that I was mistaken, the extra theming bonus on the wonders was not affected by the Aesthetics finisher, so it was 20, not 25.
That being said I never counted the culture and tourism from the other two great works, because I assumed they could be used be dumped into a pagoda or so and provide the same effect. I dislike you counting the base culture from the buildings, it's not like we are building a new city from the ground here, we are adding pop to an existing building.
Now moving on to the Museum, I don't know about you, but in my last game I've pretty much always managed to fill up my museums anyways, so I'm not counting the spare great works into a museum as a replacement, here I'm counting the Uffizi as a place where you move great works into from your pagodas and whatnot after you've already filled out your museums (or before you get your museums).
By the way I think I've isolated where some of the confusion both involving this discussion and the one earlier about the Parthenon is coming from.
In case people did not know this (and it is a vanilla feature as far as I remember) the theming bonus you get from filling out a wonder/building actually provides culture as well as tourism.
Let's use our friend the Uffizi as an example, filling the Uffizi out with 3 great works of art from the same era gives you a theming-bonus of 5 culture, as well as a theming bonus of '+6', that '+6' does not actually mean +6 tourism per turn, it means +6 tourism per turn AND +6 culture per turn. Adding the Aesthetics finisher on top of that does not change the theming bonus of 5 culture, but it does increase the '+6' to '+12' which means +12 culture and tourism.
As a final grand total a fully filled Uffizi provides you with '+3 culture +6 tourism'(3 artists) +2 culture (base) +5 culture (theming) and '+12 culture +12 tourism'(theming). Total value is 22 culture and 18 tourism.
