on intel cpu's is there any difference. I take it they are both 2 core processors

To the best of my knowledge,SS,Core 2 Duo is the latest version, and Dual Core is the 1st version of 2 core processors. Not sure on performance stats, but would guess Core2Duo to be the better option. Just to make things worse, there are now Quad Core, which I'm sure you're aware of.

AFAIK Core 2 Duo are 64bit compatible whereas Core Duo are only 32bit. All Core Duo Processors have 2mb of Level 2 Cache whereas all Core 2 Duo starting with T7xxx have 4mb. Also the Core Duo's beginning T20xx only have 1mb of level 2 cache and Core Duo's with T2x5x and Core 2 Duo's T5300 and T5200 have a reduced FSB of 533mhz as opposed to other models which have a FSB of 667mhz. The newest Core 2 duos are marketed under the Centrino Pro label whereas the rest come under centrino duo. Basically Core 2 are better than core duo models I believe due to improved architecture but just go for the best you can afford.
