Wii gaming in 4k

Actually, you don't need a titan to do that level of IR multiplication. I'd say that you would need only 4 GB, which would mean the R9 290 and 290x would do well, along with the titan. And, even then, 4 GB is quite the exaggeration with dolphin, and you might only need up to 3 GB, which opens up the 280x, 780, and 780 ti, plus probably some more. Plus, all of these mentioned cards have the needed core/mem speed required to handle that mass amount of AA and IR, so, really, your options are more open than you seem to think.
