3gb vs 2gb dual channel

[firephoenix]

Hi, i think i've only posted once bt i read a lot around (dont post bcuz i dont know that much ). I've got a question, what's better: 3gb ddr2 vs 2gb ddr2 in dual channel?
Thing is my mobo has 4 memory slots and i have 4 512mb ddr2 corsair memory and i also have 1 gskill 2gb memory, so, thing is that i want to use this thing mainly for games and stuff, maybe some small video editing and graphics stuff, nothing serious though, so i can install 2 512mb ddr2 + the 2gb ddr2, or 4x512mb in dual channel.
What's going to be best for me?

I would go with 3GB. The effect of single to dual channel is pretty small and it almost does not affect games at all.

Thanks for the answer so quick

You're very welcome.

Maybe you can also try both.
If there's no noticeable difference running a few programs, then 3GB would be preferrable, say, some day you want to run a virtual machine.
