Yeah, Apple has been using DP since 2008. I've been using it for ages with my macpro on my audio rig. Not a single problem.
I really wish I could put one of my 5870's in my mac...I wonder if the 6870 will be the first card to work on both?
As to DP and eyefinity, we are a year later, so they have had a year to work on drivers...or right...Eyefinity is HARDWARE-BASED, not software, so drivers have little effect.
Anyway, it's been a year, and I still have issues. I have issues when using DP alone, nevermind using multiple monitors...anyway, I think it's ME relating my problems, and what I think causes them, that has some people thinking that way. Nobody else, really, besides me, is tlaking about eyefinity as a problem. Mind you, I'm one of few people acutally using Eyefinity, so that's not surprising.
Crap. and I played BC2 with Reayth last night...forgot to ask what card he's got...
