I'm not sure about a 3rd card reducing your stuttering. When you get the stuttering what does gpu-z show the problem as? Is it maxed core or memory? I would save up your money and buy that sweet system a legit GPU. Get a 980Ti or, if your stuck on AMD, a Fury X or whatever new cards get released by the time you've saved up some cash.

I turn my car example at high speed bam gpu usage drop and fps drop. Like maybe the gpu cant load the texture fast enough or same as a cpu bound scenario would feel like when everything blow up.
vram at less than 2300mb with about 500mb for window. about 1300mb vram for beam ng
Arma 3 use 2300-2400 and run like perfectly
I expect to upgrade to a 980ti equivalent or better in a years and put those 7950 in the rigs im building if everything go well
There have been legitimate cases of tri-fire showing improved frame times over dual card setups, but this was before the frame pacing fixes and it probably isn't applicable now. It also won't help if there is another underlying cause.

The crossfire bridge is used for transferring frame compositing data and past a certain point (resolution, frame rate, and possibly compressibility of the frames) it's bandwidth becomes insufficient.
GTA V also streams in assets fairly constantly, and any bottleneck here can be exacerbated by CFX.
Of course, the game doesn't really like CFX much in general...

Is this GTA V? What settings?

Gta v on mostly high setting with almost 100% scaling from 1 to 2 gpu at 5760x1080 Going in straight line go perfectly even at 100mph but turning fast cause drop in most game i can run in straight line but if i move it stutter
Maybe it the Bandwith it do make sense in someways but Sli Titan x dont have that problem and use a bridge i think?
Btw i never touched cc except to enable crossfire and unknow game support think just under it and it worked fine for 90% of my game ( i go windowed if it wont work )

Pre-XDMA CFX only efficiently transfers frames for compositing over the CFX bridge interconnect.
SLI is more flexible. Indeed, there are SLI setups that work without the bridge at all.
That 5760*1080 resolution may be starting to push the limits of bridged CFX. CFBI bandwidth is only ~900MiB/s and a frame of the resolution you are using is pushing ~24MiB in size. With each card rendering every other frame, things are going to start to break down at about 80 total frames per second, unless the frames are very compressible.

Yea well my plan was to get the gpu for testing purpose and sell it after if it did not work. But i decided to wait and put it into my new build for folding@home when i upgrade gpu.
Will look for next gen gpu
Thank you everyone
