@ cwinot, that anand link you posted no longer applies. you look at later benches with later drivers the 7### cards are way faster than that.
compare our own most recent bench to it and you will see what i mean, the performance is up.
MX5J6, if your going for the 7970 get #1 MSI #2 Asus. I have a Gigabyte Windforce 3x 7870, the GPU its self is awesome, i'm averaging 60 FPS on Ultra preset, much more on smaller maps..... but the PCB its self i'm not so impressed with, it looks and feels cheap to me and overclocking is not as good as aforementioned cards, when i look at stuff like this
http://www.overclockers.com/msi-r7870-hawk-review it pains me that i can't get close to that, that MSI Hawk 7870 overclocked is performing close to a GTX 680 on the stock cooler and on the same chip as mine, but on a much better PCB, An Asus DCU II will get somewhere near that to, if not match it.
Yes, i'm kicking my self as that GPU costs around the same as mine.
I know these are not 7970, its difficult to find good reviews of them on the latest 12.6 drivers as those drivers have not been out long, all you got to know is 7950 = 35% faster than 7870, 7970 = 20% faster than 7970.
In the AMD GPU room someone i was helping a member with CPU questions, he ran a BF3 Ultra preset bench on a 7950, 79 FPS overclocked on air maps, 19 more than i'm getting. (on the same CPU)
Just be careful about some of these reviews, there old and very out of date.
