Hey there, Noiz1212.
If you are all about performance, then go ahead. It will definitely boost the loading times. However I'm not sure how much it's worth having 2 SSDs in RAID 0 just for gaming, however since you don't care about failure possibilities and if it fits your budget - why not.
It will actually be very beneficial for games with a lot of in-game loading screens e.g. like Skyrim.
Hope that helps.
