Radeon HD 7990  vs GeForce GTX 780 

Overclocking works very well and reaches the highest clocks of all GTX 780 cards we tested so far.

its 2x 7970 in 1 card basically which is old tech (1-2 years) 780 is relatively new, The 6GB of Vram will only help when gaming in higher resolutions...1920x1080 only needs 2-3GB which is perfect for the 780..but as soon as you go 4k... FPS gain from that 780 will drop big time
also Everyone forgets about those Reference coolers...they die very quickly, clog up with dust very quickly, they get much louder as time goes on. So Automatically for the small price difference the triple fans 7990 wins by default.
where? i JUST was on there site, a computer with a 7970 costs $422 to upgrade to a 7990 and thats with a supposed $700 off going on right now just for november. so if you buy a computer right now from them you have $290 cost for the base 7970 plus $422 upgrade fee to the 7990 resulting in a final cost of $712, and if you buy after november thats $1412 for a 7990...................................... so no you cant get a 7990 in a build for $300 from them only a 7970
You can get a 7990 in a build on ibuypower for 300
a 7990? it must be used then since the cheapest online right now is $700, that or you actually have a 7970 which is $300 and scores under the gtx780 a little. that puts the gtx $200 cheaper. or you can get two 770's for the price of the 7990 and destroy it.
That's wrong because it depends on where you buy it, just got mine for 300$
that's wrong because it is only $20 more
Or if you don't want to start a fire. Personally, I would only consider a 7990 if I had a water block on it.
HD7990 crossfired??

Still depends. If you are going for a quite rig it would still be better to go for the 780. You will see a decrease in price relatively soon once the next line of AMD cards are out. The reason for the price decrease was for the release of their next line.
now prices are almost same $ 659 and $ 649 . $10 different makes 7990 way better.
as of now, the 7990 is the obvios choice because its much better in most ways and only $80 more
Yes it's but the Price is the subject, to use dual SLI GTX 780 it will cost $1320 and single Radeon 7990 cost $1020.
Isn't the 7990 dual core? Then 6GB / 2 = 3GB = _same_ amount of money. This is pretty basic folks... :p
