Even if you aren't ocing, put powertune to max (+20%). I don't like the way that AMD does TDP throttling, compared to Nvidia. You can also try to turn vsync on.
If you are Ocing, make sure you don't have the ram too high. Supposedly w AMD, too high ram can run fine but be throttling itself internally. On some threads I see people don't get any more benefit past 1400 anyway.

I didn't have to do much to switch from Nvidia to AMD... just uninstalled the drivers, rebooted, and installed catalyst 12.6, and later on 12.7. I didn't try the 12.7b.

stuttering might be due to card shifts between 2d/3d clocks.
Turn off aero interface.
check no software is messing with the 3D clocks, browser, youtube etc..
use msi afterburner to set 3D clocks so the card dont downclock if thats the issue.

Setting 3d clocks is just simply ocing in afterburner or is there another way you are alking about?

Do u mean no benefit from ocing memory on gfx card?

Sorry for the noob questions

yea, just to make sure card go 3D all the time.
stuttering can be a lot, software, windwos aero, youtube, some hardware compability, nailing down the issue is a timeconsuming thing.
a need to flash new bios in motherboard is common due to vga compability also.

Supposedly with the DDR5 memory, if you go higher than it can really do, it might not show errors, because of ECC on the memory bus. I also heard that the memory ends up throttling back in order to limit errors, which may make it stutter.

For what I've heard, to find max memory speed when OC'ing, find your max core first, then benchmark the memory, adding more speed each time, until you see no more, or very little increase in FPS.

I haven't done that yet, so i run close to stock memory speed.. plus I was getting an issue with 2d as mentioned before that is related to the 12.6/12.7 drivers.

So, I am not sure what is the best benchmark to use to test out where the memory maxes out. Anyone have any recommendations? Heaven and 3dmark11 are nice, but it takes too long to keep running it over and over! Anything shorter that can help us determine max memory speed?

I don't know what to tell you man. I went from SLI 580 Lightnings to my CF 7970's and the performance is vastly improved. I didn't ever get any MS on either setup and the fps now are about 40-45 fps higher than with the 580's. You got something going wrong in your rig because AMD cards work just as good for me as Nvidia (minus various specific driver issues)...

I am going to try the 7950 on my mech drive. The only 2 things i have added was my samsung 830 and this 7950. I did a furmark test with 8xaa and the GPU hits 99% during the test. I do notice in games it does not hit 99% lots of fluctuation. I am going to try my mech drive to see if possibly it could be my SSD. Never know

Please, stop using furmark as any representation of a valid test. About the only thing it's good for is heat testing.

That said, I've got no idea how to help you w/o knowing what driver/CAP, "how" you overclock, how much overclock/voltage, etc?

20% - Stock - 12.7 (The newer version)

 

I will not use furmark anymore. Also as for CAP. I thought the Cap was only for crossfire. My problem is this. I am not getting smooth game play at all. At the moment im stumped with my setup. I have tried everything humanly possible to figure it out. lets say you straff side to side you can see it skip. Not like Vsync being off it just skips. like a split second hang. It does this a little while just walking straight also. 

 

I also notice that every once in awhile my desktop will flicker. just for a split second. I used onboard for a week and never encountered this.
