oh really?? f*ck off nvidia fanboys
Not really.
1,000 $ ??? go to hell nvidia with your 320.18
I need 2 7990s. One for my computer and the other one for decoration, its so damn sexy!
Because drivers of nvidia are worse and the reason why my gtx 760 will be replaced in a couple of months?
Why don't they take into consideration that AMD has glitchy drivers, and the quality of the drivers of each card?
I calculated the amount of money you would have to pay more for a period of 10 years of use, 10 hours a day ( the annual home electricity ) for the use of the 7990. You would have to pay 451$ US over that 10 years of period MORE than the Nvidia 690. there is a difference of 101 Watts between the two. and 101 Watts = 45$/year ( 10 hours a day ). Ive also calculated this for the Intel VS AMD processors, and I have more MHZ total over that same 10 years period, for the total price including electricity, With the INTEL processor over the AMD one, but by very very close! Which at the end, It's more of a question of choice when AMD consumes more but cost less when Buying. Things are great, I wanted NVidia Anyway!
ive been looking for 7990 vs 690 for quite a while now and it broke my brain. the 7990 is more powerful - the gtx is more beautiful - both have an exellent build quality and longetivity - drivers are fine - more sophisticated physX for nvidia - If they consider energy cost at gpuboss in their final note between the 2, because It plays a big role here. I believe Its taken in consideration. Other sites cited some image quality and Vsync to be better with Nvidia. I'll probably pick up a 7990, but Ive never tryed a Nvidia of my life, which could be a good opportunity.
no Only 2 ways
it's possible?690 4ways sli or7990 4ways crossfire?
Yea but GTX 690 is alot stable, and will last much longer!
7990, radeons are ALWAYS mroe powerfull
7990 is the obvios chouch because its $300 less even though better performance (and looks cooler)
7990 beats 690 without overclocking really...
7990 has a really good potential of Overclocking, if you will overclock it, it will pretty much beat the GTX 690
7990 for mining 690 for gaming?
