I think and hope that you'll love it for gaming.
I would try 1 capsule and 2 capsules at a time and see which way you like it the best.
There are times I take 1 capsule at a time and times I take 2 capsules at a time, it just really depends on how I'm feeling mentally at the time and how much of I feel like I need to accomplish whatever I'm doing.
Lately, I've started using 1 capsule per day every day for the memory aspects of it.
