(Why test with cable scores high than without cable?

Because it will not be the same scores at different times. It will between about 7200 to 7399. So actully. it dosen't mean that the scores with cable is higher .)

Really nice test, btw I would like to see with a more powerful card like oldie 7970 or so

Yes, I also want to
But I only R9-270X
I dont have a higher level of GPU

This is just not making any sense to me. I really can't find a reasonable explanation ...
