Re: this vs that
If you're tight on budget or want 2 more cores for additional tasks not-strictly-related-to-gaming, like video editing or 3D rendering and the likes, go for an X6. If you're up for some gaming in the most proficient and performant sense of the word, go for Intel.
It's not all about performance and, at the same time, it's not all about productivity, so... either option will be good.
But as you need an opinion and not a plethora of different arguments... my personal opinion? X6 1055T, better value for your money.
