HD6990 VS HD7970

Hello guys,

I am planning to buy a new GPU and I saw on many reviews that the HD 7970 is better than the HD 6990.
But if I compare some gameplays on youtube with these cards i see a big difference.
On battlefield 3 Ultra Settings is the 6990 more than 30FPS faster than the 7970.
So I was a bit cunfused and searched on google why many people like the 7970 instead of the 6990.
I rood on the internet that the 7970 has DirectX 11.1, runs cooler, overclocks well...(or is there more difference)
But finally what does it mather, if you overclock your 7970, the 6990 is still more than 20FPS faster.
And the temperature isn't really an issue for me.
For me there is only one point that mathers, thats how long i could play almost every game on max settings full HD 30+FPS.
I would also use the Lucid Virtu MVP software with a processor HD4000 or HD3000.(Maby is there difference if you use a card)
Why these 2 cards? because a friend of me sells these both for each 300€, so there is no price difference.
What I also saw that some games like crysis 2 dont support a card with 2 cores or something.
Dont really know if you can fix that problem or not or what to do about it.

So, hope i get some good advice.
Thanks and sorry for my english :)

    That is comparing the HD 6990 to the HD 7970

    The HD 6990 is much better than the HD 7970 but it sucks alot of power, so your going to want atleast a 800 Watt PSU
    an 850 bronze star 80% PSU SLI ready, and Modular
