Hello everyone, i just built a new Computer and the only thing i got left to buy is new gpu/Gpu's. The ones i have been thinking about are as listed.

2x Crossfire 6870s
2x Crossfire 6950s
2x Crossfire 6970s
Single GTX 580

I wanted to get Crossfire at first but i heard a lot about Micro studdering and i don't know if i want to have that problem but if it isn't that bad i wouldn't mind it. I play games at 1920x1080 But i will go to a tri Monitor set up if i get Crossfire. Throw some suggestions at me here is my rig.

Cpu= I5 2500k OC to 4.00 GHZ
Mobo= MSI P67A-G43 LGA 1155, Intel P67 chipset
PSU= Corsair 850Watt
Case= Inwin Dragon rider
Storage= 120 SSD, 4 tb Hard drive

So what i am seeing here is that Nvidia don't Microstudder as bad I already have a GTX 560 ti laying around the house should i just pick up a second one of them? I was just going to sell that card though with my old rig

Okay, with those specs above and you want using 3 monitors (eyefinity), right?
If that so then absolutely go for 2x HD6970. Dual cards setup also help a lot for reducing micro stuttering...

The issue presets in both AMD and nVida and if you read the article well, the problem is not noticeable with strong GPUs such as HD 6950 and GTX 560Ti. and the microstuttering is olny seen with SLI/CF setup not a single GPU.

6870a are excluded because of microstuttering and the VRAM size. Going Eyefinity requires a strong GPU with 2 GB VRAM enough to deal with the 5760x resolution in order not to have a framebuffer issue.
i always recommend a 3-way CF for eyefinity to run each game smoother without a lag of FPS.
a GTX 580 is not capable of running 3 monitors. the nVidia 2d/3d surround requires two GPUs in SLI

if you're not going eyefinity a single HD 6970 will do the job and max out any game out there.
AMD 7K series are the new XDR2 rambus memory which is twice faster than GDDR5, 28nm process, 1 GHZ GPU frequency. a high end GPU such as HD 7950 is expected to perform better than HD 6990

TWIN FROZER II is great and the Gigabyte with the 3 fans is also great.
the Asus Direct CU II is marvelous but it takes 3 slots that's the only problem.

Micro stuttering is noticible always if a 1 card configuration is under 25 FPS in a game.
However it depends HIGHLY on many more factors than just that, so its a bit hard to guess if a person will notice it or not.
The reason why over 30 fps its hard to notice is becouse the extra speed dims the effect, making it hard to spot, however very fast/trained eyes will still notice it.

Personally im using now a 560 Ti, with a 775 socket.
If next generation turns out to be amazing, ill change everything. If only on cpu, then i might consider SLI once my games start lagging.

The good thing about micro stuttering, is its a driver related issue most times, and so when the "final" driver realese comes out, its significantly improved.
So much this is true, that i was running Crysis 1 on my SLi 6600 GT setup on high settings not noticing micro stuttering.

if you already have one 560 Ti, there logical option is a 2nd one. The cards deliver the following FPS in Guru3D's Gaming test Suite (single - SLI):

560 Ti

560 Ti * (455 - 792)
560 Ti Cu** (495 - 862)

* Reference @ 832 MHz
** Factory OC'd to 900 MHz

The cards easily OC to 1000 MHz with adequate cooling

6950

6950 (479 - 751)
6950 Frozr (484 - 759)


6970

6970 (526 - 825)

A single 560 Ti will handle most games but some it just ain't enough

580

580 (881 - 982)

I listed the 6950 and 560 factory OC'd models since, as might be expected, these have the most OC headroom. The higher end cards are factory OC'd to 4-6% max while the 560 for example is available at up to 15% factory OC's. You'll note that the 900 Mhz 560 in SLI even beats the 6970. With twin 900 MHz 560's costing as little as $410, it makes that $500 580 hard to justify when the 580 loses by 40% to the $90 cheaper option. But this is all at 1920 1200.

In a single card configuration, all these cards will play just about anything adequately but there always is the exception. The only card top break 30 fps in Metro 2033s @ 1920 x 1200 is the 33 fps for the 580. In SLI / CF all break 40 fps

At 2560 x 1600, I'd lean towards the twin 6970's though it's a helluva lot more dough. I'd be hesitant to put any 3 cards in CF as historically the advise has been to max out w/ two cards in CF.
