iMAC 27" microprocessors???

I am gonna buy an iMAC 27" tomorrow (I already booked), the question is what kind of microprocessors comes with this 27"?
I mean on the website of this Apple reseller it says:

iMac 27” (MB952)
■Procesador Core 2 Duo de Intel a 3,06 GHz
■Caché 3 MB de caché de nivel 2 compartida
■Bus frontal de 1066 MHz
■4 GB (dos SO-DIMM de 2 GB) de SDRAM DDR3 a 1.066 MHz; admite hasta 16 GB
■Pantalla ancha de cristal líquido y matriz activa TFT brillante (visible) de 27 pulgadas de LED
■Disco duro Serial ATA de 1 TB y 7200 rpm
■SuperDrive con carga de ranura de 8x (DVD±R DL/DVD±RW/CD-RW)
■Procesador gráfico ATI Radeon HD 4670 de ATI con 256 MB de memoria GDDR3


OK, then when the seller sent me the email with coset etc, he also sent me the following details:

MB952LE/A
iMac (27" LCD/3.06GHz DC/4GB/1TB/SuperDrive/ATI Radeon HD 4670-256MB/AP/BT)



My question now is if that 3.06GHz DC means DUAL CORE? on their website it says very clear Core 2 Duo on the specs. I had a look on the internet and it looks that Core 2 Duo is much better than Dual Core. So does anybody know if 27" comes with only i5, i7 and CORE 2 DUO? or Is there a chance it comes with DUAL CORE?? are they fooling or cheating me??

Thanks for your reply and help, if your reply is befor tomorrow it will be much more appreciated!!

Yes, the 3.06 GHZ is an intel core 2 duo.
The more expensive ones are the i5s and i7s.
Believe me, the 3.06 core 2 duo is a pretty darn fast processor
