Hi.

I'm having a hard time to decide which graphics card to choose.
Since I'm gonna primarily play BF4 on my computer, Nvidia is out of the question since I want to take advantage of the "Mantle" feature coming in December for BF4. The HD7970 and 7990 are ready for "Mantle" since they both are GCN's, and they are also able to be paired in X-fire with the R9 280X later on when/if I feel the need for more power and have the money (at that point I will probably have to upgrade my PSU as well). :p I don't need the free games that comes with the "old" cards, so I don't take that into consideration. The R9 290/290X might be too expensive, but since the prices are only rumors and it's got 512bit RAMDAC I still keep it in my thoughts.... And because of the "AMD TrueAudio", but is that REALLY gonna take off and become something??? Are there any other new features I should take into consideration with the R9's vs HD7970/90's?
My max budget is $1.000 but wouldn't mind getting of with half of that if the alternative will be able to run BF4 on Ultra/Max in 1080p, and just upgrade to a X-fire solution down the road when more power is needed.


These are the cards I'm considering with the one on top being my first choice so far, and rated downwards after what I'm considering (Live in Norway, so I've converted the price to $)...:


ASUS Radeon R9 280X 3GB GDDR5 (I like this one over other versions of 280X because it's supposed to be more quiet)
$441.50


Sapphire Radeon HD 7970 GHz 6GB GDDR5
$715.84


Sapphire Radeon HD 7990 6GB GDDR5 (This one I can get hold of just the card "demo"- used for 20% less then retail price)
$786.68 (discounted price)


Sapphire Radeon HD 7970 GHz 3GB
$533.17


And as I wrote earlier; NVIDIA is out of the question!


This is my build as of now (Max total powerdraw ever registered is 478W):

Chieftec Nitro Series BPS-650C 650W PSU
ASUS P8Z68 Deluxe/GEN3, Socket-1155
Intel Core i5-2500K oc'ed to 4,3GHz
Corsair Vengeance DDR3 1600MHz 16GB CL8 (4x4GB)
2x Corsair SSD Force Series GT 120GB 2.5" in RAID 0
2x Sapphire Radeon HD 6850 1GB GDDR5 in X-fire
