If you have 3D vision setup, and you was actually satisfied with GTX580, your best option is to downgrade to 580 ('s). From your videos, i see constant stuttering (but maybe that's monitor problem, ghosting? or maybe cam?), but picture is more clear on 560. I used nVidia cards for a long time, very few ATI/AMD, mostly mid to low range cards. You know on all forums people talk how nVidia drivers are superior to AMD/ATI, and that is true, pure fact. It has more features etc, but too much optimisations can bring more problems than gains (in mine opinion). So i went for AMD again (few days ago), first things i noticed: some games have less FPS (few) than nvidia similar card tested on same PC even tho it is weaker a bit, better image quality (on AMD by far..., nVidia looks washed out...every single card i tested), better performance in general (despite lower FPS in some games), no more lag (with or without V-SYNC). On some games that use more CPU power, nVidia seems to be a little more smoother, but that's just a few games, and have in mind that mince CPU is very slow, but in cost of introducing even more lag (driver optimisation?). Overall, never again i will go green... maybe if they change the way of drivers and how it works, better more raw power with same performance than optimised... Anyway, if you where satisfied with 580's go with them (to save 3D vision setup etc.), or test things i said, and if you agree, sell that crap, and go to AMD. Cheers.
