I am in the process of upgrading my hackintosh which duel boots OS X and windows. I currently have one GTX 760 in my build and it simply isn't powerful enough when I game on windows. I was thinking about getting two GTX 970's and running them in SLI because apparently two 970's run much better than one 980 and for only a little more money. I have heard that OS X doesn't support SLI natively so I was wondering if anyone knew of any drivers that would fix this, or if it would even boot with two cards in SLI? I'm hoping that if there is no way to support SLI then the hackintosh will automatically only use one of the GPU's and windows will use SLI. Can someone please clear this up for me as I want to buy the GPU's when they go on sale just before christmas. Thanks.
