So i'm getting about 100-140fps on Overwatch at High Settings but I'm thinking i'll play better at 200fps. So i'm thinking of upgrading parts or all of my system and was wondering if you could help me point out the bottle necks in my setup:

Intel i7 K875@2.93ghz
16 Gig Ram
Samsung 850 Pro 256gig HD
NVIDIA GeForce GTX Titan
ASUS 144hz monitor

I forgot which MB i had...

Thanks in advance!
