this is about the closest the atomic sapphire version gets to the x2, the average framerate is very close at the lowest res, while the min framerate is still 30% faster on the x2, in other games, farcry 2, crysis, its somewhere between 30-50% faster at all resolutions at all times.
They aren't close in performances by any single possible definition of the term close at any time. Theres always an odd game that has issues with any card, COD:WAW works like crap according to reviews in crossfire, though they did use the multi-gpu option for crossfire and not use it for single card, I'd like to see numbers without the multi-gpu option, its an nvidia game and the multigpu option could simply be enabling stuff that helps nvidia cards, wouldn't surprise me.
Anyway, they just aren't close except where a game is bugged for a certain setup essentially, which are generally all fixed either very very quickly, or eventually.
in the future with harder more powerful games, the x2 will dominate the 4890 as it does now in Crysis, Far Cry 2, Stalker, etc ,etc.

dont bother at that res.
1920x1200 + for multi gpu set ups

I don't think the multi-GPU option does stuff specifically that nVidia orientated* - however you can pretty much guarantee it was tweaked and tested with nVidia hardware much more than it was ATI - so it deffinatly would be worth testing with it on and off.
* Not sure if its still in there but it used to optionally enable some stuff if nVidia hardware was detected - but those optional features wouldn't have any effect negative or positive on other hardware in relation to the multi GPU option overall.
