I was looking over the specifications of the new macbook and macbook pros, and found they are using DDR3 memory at 1066 MHZ. Correct me if I am wrong, but the memory used in these new laptops is actually faster than in apples mac pro? I am also curious about the speed difference between mac pros, imacs, and the core 2 quads inside dells desktops. How fast are our mac pros in reality?
 
Please take into account that the Mac Pro uses DDR2 Fully-Buffered DIMMs. In addition to that moving to DDR3 is going to incur much steeper latency penalties as well. There's going to be a fine mix of benchmarks where one standard might be better at certain tasks then another.

If you can run those benchmarks then please have at it.
 
what does it mean to have ddr2 fully buffered memory?

Fully buffered dimms offer better support for larger memory sizes. The DD3 modules may have lower latency, but the Mac Pro's quad channel memory system can provide more memory bandwidth. In the real world I doubt the vast majority would be able to see memory speed affecting them in anyway. It certainly shouldn't affect any purchasing decision.
