Both upgrades are $200 each.
I'm quoting myself here because my earlier post is misleading in the sense that you cannot upgrade the lower-end 27" model to a Core i7 at all.
In fact, ALL configurations of the lower-end 27" model are DUAL-core ONLY, while ALL configurations of the higher-end 27" iteration are QUAD-core ONLY!
I didn't realize that and reading through a few other posts on other blogs and forums, I see that this oversight is made more often than one might think.
The upgrade from the lower-end 27-incher to the higher-end one is actually a pretty good choice, as you get BOTH the higher-end graphics card with GDDR5 dedicated graphics memory as well as TWICE the amount of it, AND you not only go from a Core i3 to an i5, but you ALSO GET an upgrade from a dual-core to a quad-core CPU!
It definitely would make ZERO sense to upgrade both the CPU *and* GPU on the lower-end 27" iMac, as that upgrade is $50 MORE expensive, *AND* while you are getting a Core i5, it is still only DUAL-core i5, and NOT a QUAD-core i5!
For Apple to offer this upgrade could almost be interpreted as a little sneaky, which is why I am making such a big deal out of the correction of my own post!
