I see a great deal of debate between the quad i5 and i7 but nothing between the two i5's. I'm not super techy so I really can't tell what the benefits or disadvantages there are between the two. In fact, I didn't even notice that there are two different ones until I was poking around on apples site.
Specs:
3.6 i5 with 4mb lvl 3 cache and HT and TB
-or-
2.8 quad core i5 with 8mb of lvl 3 cache with TB but NO HT
*you can build identical iMacs both with the 5750 (5850m) and the 3.6 is only 50 bucs more.
