Is it normal to have only 120-130 khs with 270x?
No - you should shoot for about 48% of what you get mining scrypt.
Something is wrong...I've tried everything and nothing...1040/1400,intensity 18 and it wont go over 130 khs
Try:
intensity: 13 (or even 12)
gpu-threads: 2
thread-concurrency: 6400
Clocks should be fine. I don't have a 270x but that seems to be what most people are having success with.
