I have a 17 inch white C2D imac with 2 x 1 GB sticks of ram in it currently. And my question is if I swapped that over for 2x 2GB sticks one day in the future, would it have the dual channel effect that all matched pair sticks have even though only 3 of the 4 GB would be addressed in the mac?

And if it would have the dual chanelling effects, would this be much of an improvement to a 2 and a 1 GB (3 total) stick in my mac?

Lastly currently I have zero page outs to my hard drive with my 2 GB of memory. And I always have over 300MB free. That's just free not including the inactive memory. And I do sometimes do things such as video and audio editing and photoshop work. So if I did get 3 or 4 GB for my imac, would the performance be a little less cause those extra GBs would rarely be used?

Thats alot of if's and theory right there. It should still receive the dual channel effect as it still meets the requirements for it. 4 is still faster than 3 unless you buy lower quality memory. That said seems like 2gb is enough for you so unless you want to upgrade id say staus quo.

There are 10 types of people in the world. Those who understand binary and those who don't.

There are two types of IT problems in the world. PEBKAC and ID 10 T's.
