Does 5870 Crossfire Stutter?

I'm really considering selling my mobo and buying the similar model and going for crossfired 5870s as it seems the logical thing to do for an upgrade.

Anyone know what the micro stuttering is like for these cards? I've never had crossfired cards.. a long time ago I had SLI 8800GTXs and I remember there being a slight stutter but I can never remember if it was gfx or cpu related at the time.. due to the overclock I was running.

Including the HD 68xx and HD 69xx cards?

Do you have a link for any supporting evidence?

Ill just find the link.

It is noticeable that a single GeForce GTX 560 (no Ti suffix) is subject to more pronounced frame rate variations, even while the frame rate itself is almost identical.

In this particular title, SLI doesn't scale as well as CrossFire, resulting in a lower average frame rate than two Radeon HD 6870s in CrossFire. The Radeons, however, suffer from visible micro-stuttering, while the slower GeForces subjectively seem to be faster due to the reduction of the phenomenon.

We've run a number of other benchmarks and need to add, for the sake of fairness, that Nvidia's advantage is only evident if its driver is optimized for smooth frame rates rather than raw performance. The company takes certain apps, like synthetic benchmarks and commonly-tested games, and tweaks them to yield higher numbers at the expense of consistency.

Interim Assessment

Nvidia gets an advantage here, though its cards are slightly more expensive. SLI isn't scaling as well as CrossFire in Call of Juarez, but it does deliver a more balanced sequence of frames.

Scaling AMD 6xxx -NV- AMD 5xxx lower scaling seems to have less micro stuttering, the 5xxx scales less well than the 6xxx.
Tri fire gives the best results and very likely TRI SLI.

i went from a 5870 cf to gtx480 sli and i wish i hadnt as i never noticed micro stutter with the 5870,the gtx480 on the other hand is so bad in most games that i usally jst disable sli,so go ahead my friend as its a great little setup
 
Been running crossfired 5870s almost a year now and thorough recommend them. Never noticed any stuttering, theoretically it must be there but I haven't noticed it. Never had any issues with the cards at all, in fact.

I'd say try to get a motherboard with the PCI-E slots 3 apart (so there's a gap between the two slot coolers for airflow) but then I stuck a Xonar DG between them so I can't talk!
 
Great advice and comments guys, just what I was after. I think when I get paid next I'll be getting a new mobo and then another 5870 :)
