HD 5870, but which brand?

I thought I had seen a thread with this title or similar title, but I can't find it if it exists.

Anyhow, as all the new HD 5870 cards seem to be the same except for name and the outside graphic, is there one that's better than the other?

They're, of course, all sold out on NewEgg, but once available again, I was thinking I'd order the XFX card. Is this a good choice? Or is another brand better/more trusted?

Thanks!

The same thing happened when the ATI Radeon HD 4770 was introduced earlier this year. The cards were all built to the ATI reference specifications. It was a few months before XFX came out with a 4770 with a different fan shroud that exhausted warm air out the back of the pc case.
