It's just a single core with hyper-thread.
Funny thing is... your computer is better than mine.
I got a 3.0ghz single core intel cpu. With a 775i65g motherboard. I've been trying to find a Core 2 Duo E4700 but they don't sell them any longer. A few weeks ago i found a ddr2 motherboard in the trash someone had thrown away. The problem was they had destroyed the cpu socket so it was unusuable WHY?!?!
