Wow, that graph of framerate with the "runt" frames omitted is incredibly damning. You're effectively no better off using Crossfire than a single card.
I wouldn't call it "damning" by any means.
Limit the frames to 59FPS and you have a different story, no? What's the point of the 80-100 frames on a monitor with a 60hz referesh rate, anyway?
I really want to see more evidence regarding this issue. It's baffling to me that this chart basically says adding a 2nd 7970 does nothing.
Yeah im smelling bullshit here lol. Running 3892x1200 resolution here and that second 7970 is definitely doing something.
Take out one of your 7970s and see what your frame rates are like. Don't even go by FRAPS or an on screen FPS visual. Just test the general smoothness. Pretty sure this would have been discovered a LONG time ago if people upgraded to their 2nd card and didn't notice a much higher responsiveness using the same settings. I'd really like to know because I sold my rig and I have purchased everything except the vid cards for my new rig. This data has me NOT making a purchase until it's confirmed or debunked.
Crysis 3 is a stutter fest without the second card. As long as you limit your frame rate to 60fps (not vsync, use msi afterburner to lock the fps at 60) you will not get microstutter.
EPOQ I was in the exact same situation about four months ago and went with the 680's.
AMD had already released their latest driver update which made the 7970 ghz the better card overall compared to the 680 and still went with the 680's because SLI just feels better over Xfire. I have the 2gig versions EVGA FTW 680's and the performance at 2560x1440 is stunning and buttery smooth. Crysis 3 with no AA is 60+ FPS for the most part. the first level chugs, but that is because of poor coding. Very high settings for everything. Card is OC'd to 1254 with the memory at stock.
Every other game that isn't optimized like **** runs flawlessly. I am sure you will get similar or better performance with the 7970, but the lack of smoothness is a deal breaker for me.
Just my two cents.
The F2P cash bundle from nvidia isn't as good, but it isn't bad either. If you are into PS2 it's a lot of in game currency.

No, I don't believe the answer is that simple....but why the decision for all next gen systems to choose AMD over Nvidia. The answer is simple, AMD makes excellent hardware as well and Nvidia just cant compete with the price to performance ratio.
I had Crossfire Eyefinity right out of the gate and always felt there were horrible issues with smoothness that went beyond framerates. Switching to SLI was night and day. I would be very reluctant to touch Eyefinity or Crossfire again without seeing it first-hand.
These posts regarding stuttering, smoothness issues has been addressed by AMD in the last month, I can assure you that from my personal experience a vast improvement in less then one month.
All I can say is I can play the latest and greatest games with no stuttering outside Rage in Xfire
A few select games is not fixing the whole problem, just ackknowledging and addressing certain games to look like it's getting fixed. I've been saying this for years as well.
I just don't get it. If you are capable of seeing high 50s to 60fps at all time in CF, why the hell can't you just play with Vsync and or use the Frame Limiter in Radeon Pro or Afterburner and nip this whole thing in the bud and end the conversation. The stuttering only seems to be an issue when the frame rates are all over the place. Yes, you may have to change it to address certain games where you aren't capable of maintaining that same # of frames, but it doesn't seem like that big of a deal. Not to mention, the more this is brought to the attention of AMD, the more likelihood in them creating a more permanent fix.
