Will super clocking help my frams?

Hmm, you should be getting more than 50 from what I've seen. 1920x1080 res? EDIT: around 50 is actually pretty normal on ultra. You'll get to around 60 by playing on high.

You will see an increase from overclocking but I'm not sure how much. Maybe 5 (maybe a little optimistic, not sure) FPS with a decent overclock? You don't even necessarily need something as expensive as a corsair h series but it's up to you.
