Why is my XFX Radeon HD 7990 performing so slow?

[bzer0b]

Title says it all. I only get about 30-40 FPS in GTA 4 maxed out.. Same for Battlefield 3

My specs:
AMD FX-6300
XFX HD 7990
8GB RAM
ASRock 970 Extreme3 R2.0

I am also experiencing slow frame rates and buffering in a few games namely Arma 3.

I am using 2 x Gigabyte 7990's which makes it 4 Tahiti GPU's.

I thought I would hit the googlizer machine and see if anyone else is having issues which does seem to be the validated.

I am using these components; Asus sabre tooth mainboard with 16 gig 2133mhz ram with a AMD 8120 CPU and a total of 2000watts of power (1350/650 PSU's) with all the latest drivers water cooled etc.

I'm tossing up whether to go out and buy either a 2011 or 1150 socket mainboard and CPU more than likely a 4770k to help with what seems to be bottlenecking.

When I'm playing Arma 3 all of a sudden the game will slow right down to a halt (which is what I think is buffering) then it will come good about 2 seconds later. I also find that as game time goes on the performance gradually gets worse and worse.

I'll try the new motherboard and CPU combination and I'll post what I find. Failing this I will buy a gtx780ti

I understand most games aren't optimised for duel gpu let alone quad but this runs deeper than that,

Hey Hummers....
I also have a 7990 quadfire. On top of that I have a i5-4670k@4.5GHz... everything is watercooled.
BF4 runns beautifull on Ultra, 1080p Resolution scale@150% and over 140fps.
But in Arma 3 I get like 30fps.

Tell me if you had any luck with the 4770k... I might be going the same direction. Thanks!
