As Khatarian said, going RAID 0 with SSD's isn't going to be too different for what you intend to do. You probably won't see that much of a difference from RAID 0 compared to a single SSD in real time. Another good point Khatarian said is the headaches with RAID sometimes. I'd say use one SSD for your OS, and the other SSD for any frequently accessed apps/games. That way, in the event one of your SSD's blow up, your RAID won't completely be demolished and you'll either lose your OS, or a few games/apps.
