It's also hard to know how much of it is rehashed out of date info that no longer applies, and how much is just pure FUD. I'll give it a go in SLI anyways, since I personally haven't experienced microstutter since the 400 series.
It used to be indeed very bad in eyefinity and CF, that is one of the main reasons why I stopped doing CF and have been strictly with single cards last few generations. However, with Occulus being sort of like single screen 3D it should have no more issues than any other single screen 3D setup in that regard. Claims are that the situation has been improved a lot after the issue was dragged into light causing companies to pay a bit more attention to this issue than just having as high as possible average fps.
Anyway, depending on what kind og GFX settings are aimed a single higher end GFX card should be able to offer acceptable frame-rate even at very high resolutions. I'll throw up couple of screenshots into the spoiler box from the "Lost coast" benchmark I was talking about earlier:

Just did a rerun for these. surprisingly the FPS was lower than I remembered. The average was exactly 120. Resolution 10 megapixels (25% higher than 4K) every slider as far as they go. I remeber getting 202 fps last time I ran it in similar situation, dunno why it's different atm. Perhaps I had lower AA setting than I remebered or the issue might be that I just had a crash so my Raid 1 array got corrupted and the Steam folder is on that array as well (it's fixing itself atm giving HDD's a lot to do). Anyway the point I am trying to make that while the engine is old and is not exactly knocking your socks off 2014 a decade after its release it's not THAT bad either and VR can add that extra layer of immersion so I would be willing to give up, say, Metro 2033 or Crysis 2 like GFX for Source like engine and VR if the experience I get out from the game just feels better. I quite do like nice GFX in games but at the end of the day I'm after entertainment.
