Motion Blur - Is it advantageous to use?

I have enable motion blur for a while now but I'm not sure if it really helps my game-play or if it's just eye-candy using resources. I notice that my aimdot will turn into a fuzzy short line when I look left or right but only on the horizontal axis. I don't notice that effect looking up and down at all. I have a 24" monitor and I'm about 19" from the screen so I think I get a natural motion blur in my peripheral vision anyway.
Is it worth enabling motion blur?

Where I would usually be a stickler for keeping everything almost vanilla so that I can fully enjoy a good looking game.. I much prefer the better clarity you get without it enabled. I would even say it can make games look worse, all that blurring everywhere you look, not for me.
It's your decision weather you use it or not, Blur will never give you advantage in killing, just the graphical diference if you like it.
Even tho, i haven't tested, being a img processing "thing" it might effect framerate negative.
Thanks.
