Micro stutternig HD 5970

[007Nix]

Do HD 5970 have microstuttering ?

Which one would be a wise choice GTX 480 or HD 5970 ?

Besides currently i own GTS 250, so i would be using it for Physx processing. Do GTX 480 run with GTS 250 for Physx?

5970 has some micro-stuttering in some games which doesn't play well with MultiGPU tech.
But it performs better than a GTX 480 performance wise.
And you can use your GTS 250 as a PhysX card with both 5970 or 480
