You can try, but you would be the first person ever to get full settings working at an acceptable framerate.

Report: AMD to Discontinue Radeon HD 7990 in Q3 2013
http://www.tomshardware.com/news/AMD-Radeon-HD-7990-Malta,23430.html


Review of 7990 in Crossfire:
Radeon HD 7990 In CrossFire: The Red Wedding Of Graphics
http://www.tomshardware.com/reviews/radeon-hd-7990-crossfire-overheat,3539.html
"When it launched, a generous eight-game bundle had me on the fence about the 7990’s prospects. But after spending time evaluating its thermals and acoustics (to say nothing about its crashes and performance hiccups in CrossFire, which could become a story unto itself), I can’t think of one reason to recommend 7990 to a friend. And, at the end of the day, that’s what this job is all about."

Yes, you can crossfire 2 R7990s, running them in quadfire.
But why do you want such a card when the new volcanic islands series of GPUs from AMD is coming out very soon.
I suggest waiting for the new flagship card to come out then buying it. It may not be as fast as the former but you won't have to deal with multi-GPU problems yet and this also leaves you open to crossfire them in the future.

Yes, you won't have the heat vortex and throttling, BUT you'll still have the coil whine (X 2):

You will also have the usual problems that affect all Crossfire setups, which are going to affect Quad-fire even more. Most prominent among these are proper game profiles and frame pacing. Without proper game support, your setup will be stutter and performance will resemble only a single GPU. Frame pacing does not work on multiple monitors, DirectX 9 games (Skyrim), and OpenGL games (Rage). In these games, again, your performance will be jittery and your performance will not be satisfying considering the expense.

" However, we've also seen many games that do not scale well, and they make up a significant portion of our tests. Out of eighteen titles, five did not scale, or worse, showed negative scaling. These are not small titles, but big AAA games: Assassin's Creed 3, Batman: Arkham City, F1 2012, StarCraft II, Skyrim, and World of Warcraft. What really surprises me is that this long list is the same as the one we had with our reviews of HD 7990 "New Zealand" implementations by board partners, like the ASUS ROG ARES II and PowerColor Devil 13. So either AMD does not care or can't fix CrossFire support with these games millions of people play."

Quote:
"What is a major issue, though, is the extremely annoying coil whine the card emits as soon as it runs a 3D application. The whine is generated by resonating power circuitry coils and is a problem that can be resolved; it's just an engineering challenge. NVIDIA did so for the GTX 690 and GTX Titan; both cards don't have such coil whine issues. On the HD 7990, however, it is very apparent, and I don't understand how AMD missed such a glaring problem. I talked to five other reviewers and they all confirm it, so it's not an isolated issue. What makes the whine even more apparent is that it is constantly changing pitch and volume, drawing your attention to it by effectively overpowering the fans' "whoosh" sound."

With the R9-290X (HD9790) being announced in a couple weeks, it seems like a good idea to hold off a bit and see what happens. The 7990 was quickly discontinued after two months for a reason. If you really want one, maybe they'll be even cheaper in a couple weeks or so.

Of course, for about the same price, you can do Tri-SLI with GTX 770s that will be a much better experience, or even SLI GTX 780s. Either would seem like wiser choices in terms of game support, smooth gaming performance, and frame pacing.

Well, the top of the line card, the R9-290x, formerly called the 9970, is targeting the performance of the Titan/GTX 780. So that would be your corresponding card.

Of course, you would need to get a GTX 780 in order to enjoy PhysX in Call of Duty: Ghosts or Batman: Arkham Origins.
