Adding more ram to mb 3rd gen

[salanet]

Hi everyone,
I want to add ram to my MB.

The question is:
Haw match RAM should I buy?

Possible answere are:
A - 2Gb kingstone memory (2x1 Gb stick)
B - 3Gb kingstone memory (1x1 Gb stick+1x2Gb stick)

Option A seams to be safer. But prices are the same and i'm trying to make the best deal....

Is better to have more memory or to have it connected though dual channel?

Thanks everyone,

More memory is better. Dual channel adds 6% - 8% overall, but the extra GB will really helpp if you are multitasking or using phtoshop, digital video or digital audio

third gen MacBook, I think it was the second gen C2D, out in may 2007, not Santa Rosa yet so you can't really max it out to 4Gb like someone else was saying..
at that time you could only put 2Gb in MacBooks and 3Gb in MacBook Pros
I think I read somewhere that puttin different sticks of Ram, that is to say 1Gb+2Gb wouldn't let you use it all for graphical rendering, and Apple wouldn't suggest you pair different types of Ram in this case while having a dedicated graphics card would allow you not to worry that much about Ram..
so,in the end I guess it just depends what the user wants to do with his Mac
