This link has the bottom end of the main i3/5/7 lines. It shows that i3 is dual core with HT, i5 has dual and quad cores (some duals have HT and some don't), and i7 is quad core with HT. The i3 line does not have Turbo Boost, but the others do. The hex cores are not listed on their website just yet, so I do not have those included.
