I noticed that i've been running low on ram lately on my mbp (have 161mb free of 2gb at the moment) & been thinking about upgrading my ram.

which one would perform better?

4GB of ram (2GBx2)
or
5GB(4gb+1GB).

I read someone where that the 2GBx2 would perform better then the 5 because of dual-channel memory support? is this true?
also would upgrading to higher ram make battery hours shorter?
