I use SSDs for practically everything. I can't say that there is huge difference when it comes to gaming, except for when it comes to load times. Many people simply use a SSD for their operating system and install games on their HDD due to space restrictions. With that being said, it's always nice to take advantage of SSD's ludicrous read/write capabilities. If you have the free space on your SSD for gaming, definitely use it.
Really hope this helps!
