Crossfire for nMP on Windows / Boot Camp

[Stingray454]

4K Crossfire is broken under dual dXXX cards for gaming. See the anandtech review. For the 1st time in 10 years, Hackintosh here I come!

Not sure what you mean, crossfire not working at 4k is a windows driver issue that affects all PC's, not an issue with the Mac Pro (might be fixed in the driver now, as the anandtech review is 2-3 months old by now). And as always, crossfire under OS X just doesn't exist yet

That said, I build a hackintosh with dual 280x cards. Works like a charm in both windows and OS X, although in OS X you can only use one card for gaming, but you do get the dual performance for OpenCL tasks.

What is 4k Xfire? Do you mean Xfire at 4k resolution? Can any card do that? That are insane amounts of data that has to be copied between the cards.

of course, because if the nMP won't play BF4 on a 72" bigscreen at 4k with 200fps, the nMP is a waste of a computer that should have never been built..

Often even my 2 D300 are. Most games I own I have to disable Crossfire because I don't need > 200fps.

Me too. I play TERA a free MMO which uses Unreal Engine 3 ( https://www.unrealengine.com/showcase/tera/ ) it is really nice quality but if crossfire is enabled I need good cooling in my room because those D700's put the system fan at full speed.
Still can't hear it over the game sound but it's like a mini heater and I don't want to unnecessarily shorten the life of my nMP so disable crossfire, still get 60 to 70fps on all max quality settings with just the one card.
