Amd is currently having high end crossfire issues so a single card is better for the most part. As for titan vs 7990 the 7990, in theory, has slightly better performance, and I mean slightly. http://gpuboss.com/gpus/Sapphire-Radeon-HD-7990-vs-GeFo.... But the 7990 is alot cheaper and actual real world performance may differ. The 9000 series flagship (9990) should out perform the titan in large steps once it comes out.

The 7990 is a high end crossfire setup, essentially not much different than dual 7970's. It doesn't matter that it is a single card. Anyway, AMD has rolled out the new drivers to fix the microstuttering issues. The 7990 seems to have heat issues as well, if the case does not have good airflow. The GTX Titan is a bang for buck loser, offering significantly less performance than dual GTX 770's for $200 more. The Dual 7970's would give you the best bang for buck, however dual 770's from nVidia may be your best bet. What resolution are you gaming at, and what types of games will you be playing?

I must have missed the driver release while I was at the coast, amd did fix the issues then? If so, then performance per dollar crossfire 7970s or sli 770 would be better.

GTX 770's in SLI is quite clearly the best choice. Even an overclocked single GTX 780 would be a great choice if you wanted to avoid the pitfalls of multi-GPU setups.

The 7990 should not be a consideration. It was such a failure, it has already been discontinued. Sure microstutter and frame latency were issues, but the annoying and pervasive coil whine was apparently a major annoyance.

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."

Crossfire issues were only partially fixed. The fix does not apply to DirectX 9 games (Skyrim for example) or multi-monitor Eyefinity setups. They also reduce performance in several games. The usual lack of game profiles still affect Crossfire, but not SLI.

Two quotes from recent reviews should be all you need to know:

TechPowerUp review of the 7990:
"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.

Guru3d's review of GTX 760's in SLI:
"But fair enough, over time NVIDIA has done a great job, micro-stuttering is a thing of the past and there are hardly any driver issues. And with triple A game titles, NVIDIA will have a driver for you at launch day ensuring your multi-GPU solution is supported."
