This is my 2011 iMac's Cinebench. It's being reported as a 2 core/4 thread. The i5-2400 3.1 Sandy Bridge processor should be registering as 4 core/4 thread. This is our 2009 Core 2 Duo 3.06Ghz. The 2009 sure is a lot faster than the 2011 in loading programs and running the OpenGL test. Both are running Mac OSX Snow Leopard. Both are 27". The 2011 has 16GB RAM, the 2009 has 12GB. The 2009 is still faster. By a lot. I think we got a lemon.
