Over here in Denmark (Northern Europe!) the Gigabyte WF3 290 is ~$16 less than the Sapphire, and it also includes a copy of BF4, something the Sapphire does not.
Sounds like a pretty good deal to me.. if only there had been any reviews of that card, I'd have jumped on it..!
Are you sure the Sapphire doesn't? The UK Sapphire 290 has BF4 included.
