Horrible performance on 2 Amd Radeon R9 295x2s!

So i built my computer right when these graphics cards came out, payed over 3500$ for them and now i feel like i just threw money in the air (like i just don't care, i know).
Every single new AAA title that comes out runs like * on them.
Except for battlefield 4 and some other EA games (also older games run well of course).
I just bought Call of duty black ops 3 yesterday and saw that it ran fine on max settings 1440p with a single R9 290x on many youtube videos (me having 4 of them, i wasn't afraid of any fps drops).
I go in game and the game crashes, again, blackscreen and crashes.
So i go and disable crossfire (using only one of my cards now) and the game starts.
I go change some settings (put the 4k full screen res down to 1440p for 85hz and tuned up all of the advanced settings), after that i start a freerun game (obviously being a tiny level with not much to render, it shouldn't take much to run right ?), the game goes at 30fps on 1440p with one of my R9 295x2s.
The shadows are all glitchy and the game is extremely stuttery.
I imagined it had something to do with the 85hz overclock (because it happened to be a problem on other games like guild wars 2 and other mmorpgs) so i put it back to default (60hz), same performance, same glitchy shadows and same stuttering.
The only resolution at wich the game ran without stuttering (but still having the glitchy shadows and what not) was at 1080p (wich i xxxxing hate, that resolution sucks).
Now as i said, one single R9 295x2 is supposed to run the game on max settings at 1440p.
Idk if those guys over at activision are as stupid as not enabling multi gpu support on their game but it doesn't seem to be a problem for anyone else.
Oh and also, i can't connect to the servers no matter what i do (restarted modem, pc, steam, game).
My gpu temps are perfect (under 65c), and i didn't check the clocks but i'm sure that they're going all over the place from 600-1000 (wich happens on so many games).
Here are my general pc specs:
Intel core i7 4770k 4.59ghz OC
32gb corsair vengeance ram
1tb Kingston x ssd (for os and games including bo3)
3tb Toshiba hdd (for fast loading games and other stuff)
Asus maximus vii hero motherboard
Corsair AX1500i PSU (sorry if i got the name wrong cause i don't remember it fully)

P.S. The computer is very well ventilated with 14 noctua ippc 3000 pwm fans and everything runs ultra cool.
Any help is much appreciated

 
Solution
A solution you might not like, but sell both video cards, and get a single gtx980ti. Dual gpu's have their issues, 4 gpu's is just asking for trouble. That and they are 4gb cards, which isnt enough for some games at 4k.

you have ran face first into the major downside of multi gpu systems


guaranteed the majority of games will not function at launch, if ever

I would wait, Pascal and Artic Islands are going to make the 980ti look like a joke. The 980 was faster than the 780ti even though it was on the same processes node, image what Pascal might do to the 980ti.

you actually have 4 cards


a single 295 is two cards in one
