It most likely has something to do with your hard drive. They are the biggest bottle necks in a system now a days. I have two ssd. And I have noticed a slow down since this new patch though
:BS, I use my 2tb spindle drive without any issues at all.
@OP, your bottleneck is your slow-as-molasses cpu. Do you have it overclocked at all? My i7 920 is clocked at 3.6 right now but typically runs around 4.0, and I also have a gtx 460. Get an i7 2500/2600k system, those will easily go to 4.2 on the stock cooler and 4.5-4.7+ if you get really serious about it. That 1 min+ will turn into 10-15 seconds.
BTW, you might also turn your graphical settings down to mostly medium, with low tess and low res leader screens, at least on larger maps.
My solution: read a book while playing.
Frankly, it works out really, really well.

Fun fact: I finished The Drawing of Three while waiting during long turn-times in A New Dawn (CivIV mod).
And like Drawmeus said, Strategic View is a great thing. During wars, it drastically decreases turn time because you don't have to watch every single battle.
