you have to be more specific. MSI has like 8 version of that card. but for the most part they have horrible reviews from verified buyers on newegg and amazon.
from what i gather the artifacts and even failing cards are due largely to the poorly designed aftermarket coolers. the Asus Direct CU version of the 280x also seems to be suffering the same fate.
on the other hard, the gigabyte 280x seems to be getting mostly praise.
in any case. i think it is safe to say with this generation of high end GPUs we are looking at least 1 RMA at some point of ownership. i have two GTX 780 ACX cards. they have near perfect reviews and one of mine just blew up recently. literally blew up in the case with little bits of plastic laying around...
