Dunno, I never liked such hyper-intelligence in a normal human. It's why I can't stand Mr. Terrific (what was it, 15 doctorates by 20?) and similar characters. Reed can stretch his brain and become infinitely smarter for example, which is the reason why I never had a problem with, and was also okay with Doom being 2nd (not to mention he has the "touched by demons" excuse). Another example is Tony who, before genius = super-genius in every field, was just a brilliant engineer. Then he got the Extremis upgrade and really became a powerhouse.
Generally, I don't mind super-geniuses, but if you're gonna go all "eiditic memory", dong 5 tasks at the same and whatnot, you better start off lower and build up to that with some sort of upgrade. Make them essentially gods, and the character loses something. Just look at Riri and Moon Girl.
If it were up to me, Luthor would be a super-genius, but it'd take some Kryptonite-Related experiments for him to truly reach the level where he plays 20 chess games, writes a paper, buys stocks, etc, etc, all at the same time.
Also, I long for the day when writers are gonna wake up and say "our characters have trillions, and have an IQ of 500, but people still live in dumps" and go for at least a Mass Effect or OT Star Trek-esque level of architecture/design/culture.
