i7 iMac and 8 Threads?

I believe i7 in the 27 inch iMac is the intel i7-860 part. As such, it's four

cores of course and hyper-threaded so 2 threads per core.

Can anyone who purchased an i7 confirm that in fact Snow Leopard not only sees all

four cores but 2 threads per CPU core effectively making it appear as 8 cores?

Thanks.
