Suggestion for a new theme

Hello everyone there!
I’m new on envato. Right now i’m building my own site. I have some html and css knowleage, but i’d like to buy a versatle theme.
The one about i was thinking about was Avada. It seems to be a really cool but i’d like to have an opinion about it…
What i’m looking for is a theme for a gaming site and pc componets etc with reviews, blog, ecommerce and BBPress.
Does it worth? Which plugins also i should buy? Like uber menu etc?
