Faster SSD: For OS or games?

[Khiyon]

Hello,
I've been searching for an upgrade for faster loading times in games, especially the open-world ones.
I've already an HyperX 3K SSD 120GB for the OS and the games on a Seagate Barracuda 1TB HDD.
I was looking at the Samsung 850 Evo 250 GB as a SSD for my games.
My question is, should I change the OS from the HyperX 3K into the Samsung and have my games in the HyperX or have the Samsung, which is newer and faster, for the OS and the games on the separated HyperX SSD?
Also if you have any other SSD recomendation (around 100€), it will be taken in consideration.
Thanks in advance.

When on sale, you can grab even 750GB version for the 100 pounds. at least 100$ was the price for 750GB version on last black friday.

This is just me: Limiting factor is your current 120GB SSD capacity. I'd keep the OS there (I am using a 120GB as well and its enough for OS but not for games). Not much of difference in real-world performance comparing 2 SSD's -- both will be considerably faster than the HDD. I would use the 120GB HyperxX SSD as OS (and some desktop programs like I did), use the 250GB Samsung SSD (or if budget permits, a 500GB -- depends on how many games and their corresponding GB capacity once installed) for selected open-world games (to decrease loading times), and still keep that 1TB HDD for some games (those games that are not graphic-intensive or rarely play) and for general storage.
