[Gllug] increase performance by increasing RAM or increasing in Core

[Diana Scott]

My linux box has 2Gb Ram in a Centrino at 1.7Ghz running ubuntu 8.10 32bit. If i were upgrade to the highest latest spec such as 4Gb Ram in a Dual Core processor running ubuntu 64 bit, what are the significant speed increases that can be easily noticeable apart from the speed of loading up programs ?

Would a Dual Core 1.7Ghz processor with a 2Gb Ram can be faster than a single Core processor with the same spec because the Dual Core has a double processing engine ? 

Please advise.


Diana
