Unfortunately just an opinion. The only time you'll get an FPS increase from an NVME upgrade is when the storage transfer speed becomes the bottleneck during gameplay. If a game is coded to drag textures back and forth from storage (most games load what they need into VRAM), then you may see a difference between an SSD to NVME. Otherwise your games might load faster but you will not get an FPS bump. Especially in e-sports titles like Overwatch.
