16gb 1333mhz ram vs 16gb 1600 mhz ram

Hello, so I am building a gaming/rendering rig, and I was wondering how much faster is 16 Gig 1600 Mhz Ram compared to 16 gigs of 1333? Is there a noticable diffence in gaming or say if I was rendering videos through Sony Vegas? Because if not I rather save like $20 and get 1333 ram

Save the money, and overclock it to 1600mhz. With that said, you can overlclock a decent set of RAM rated for 1600mhz then a set rated for 1333mhz. Doubt you will see much improvement, cpu overclock would give better results.

I can't speak for vegas, but in games, it will make zero difference.
