    In my PC build, I currently have 1 stick of 8GB 1600MHz DDR3 RAM. If I bought an identical RAM stick and put it in my computer, would I get better performance because it's dual channel?

    yes it's a little bit faster, but only 5-10%

    Well, yeah, coz then you'd have 16GB....:lol:
    Seriously though, yes 2x8Gb would be faster than 1x16, but not by much....
    EDIT: Ninja'd again! Yep I'd say mgrev is about right there ;)

    It depends, if you're using it for gaming with a physical GPU then no, you're probably get a 1 fps boost at most.

    If you don't have a gpu and have integrated graphics then it will give you a very nice bump in performance.

    I have a dedicated GPU... so there'd be hardly any difference at all?

    If you multitask, you will notice a relatively big difference in performance, especially if you run Chrome, that browser eats ram.

    The only game I can think of at the moment that runs slow without 16gb of ram is Batman Arkham Knight.

    In gaming you won't see any improvements.

    I read somewhere that dual channel ram increases the speed but the available memory decreases by just a bit(almost negligible)

    technically it's better in dual channel, however if you actually notice this improvement is another thing

    It was only about that fast on the nForce2, back in the 90's, because it was connected to a CPU that was only made for single-channel DDR RAM with the original AMD Athlon.

    Nowadays, with CPU's made and intended to run with such an amount of bandwidth, the gains are more significant. I certainly would not even dream of trying to run a Skylake on single-channel mode. If you have to do that, it's more likely a defective motherboard or CPU.

    The X99-based i7's practically could even go quad-channel, with most motherboards for that style of chip having eight RAM slots.
