While I do agree with you the article dates back to April of this year which is quite a long time ago. Drivers have come and performance has increased for the 7770 the 6870 is still faster however not nearly 70 %

According to this, Not much difference.

But still 6870 is better.
My friend has one, he plays every game at High 1080p easily.

So, I suggest you to get 6870.
 
Not necessary I wouldn't look at things from a team green versus team red perspective. He is looking at budget cards which means he is probably on a budget. I'm still sticking with sumu's recommendation.
