True Immortality. That includes indestructability, immunity to death, eternal youth, etc not just eternal life as it has often been (mis)represented as. If something can kill you, then you are not immortal, so if something that can destroy everything came along it would be a case of irresistable force meets immovable object.
Second power would be the ability to teleport anywhere, then I could travel the universe and not worry about ending up somewhere inhospitable.
This is the power I would absolutely NOT want - human psychology isn't built to cope with billions of years, and billions of years is nothing compared to eternity.
You would live to see everyone you care about die, and as you make new friends and loved ones, you'd witness them die too, again and again and again, until the end of humanity. After that, you'd be alone - at best, you might find an alien species that has some vague similarities to humans, though their psychology would be likely to make them very alien indeed to you.
After countless hundreds of billions of years, in the unlikely event that you were still sane at that point, you would be floating in space, in nothingness, as the Universe winds down to a heat death, and eventually all mass slowly degrades and radiates away. Except for you, of course, floating in vacuum. For all eternity.
That might not be the end of it though - depending on whether some multiverse models are right, you might eventually end up in the middle of a big bang event, and inside another, freshly formed bubble universe. But the likelihood of that happening at any given moment is so remote, that you'd spend so many billions of years in a vacuum, that if I were to start writing down the number of years right now, adding zeros after a 1, I could go on for the rest of my life, and still not reach a high enough number.
The brief flashes of fun you might have had, as a powerful, immortal human would be long forgotten before you ever had even the slightest chance of experiencing anything but your own, immortal, mind, caged in your skull.
What a horrible, horrible fate indeed. 
For my superpower, I think I'd go for precognition - the ability to see into the future, say, just a few hours ahead. I'd be very wealthy, very fast. :innocent:
You forget that eternity would allow you to gather immense knowledge, and also allow you to build up walth and alliances through centuries, manipulate entire nations and cultures, place family members in power, simply by giving you enough time to do so.
Would not change a thing - entropy will win in the end. Hard to make stuff, when all the matter has disintegrated into radiation. The brief time there was matter would be insignificant compared to the endless hundreds of billions of years that you would be condemned to spend floating in a vacuum, no matter what you did while there was matter. Thousands, maybe more years of wealth and power - even if that would make you happy in the face of constantly having to watch your loved ones age and die - would be a mere flicker in the scheme of things.
You also assume that simply additional time would give you the ability to do quite a few great things - yet time alone cannot change your habbits. Are you motivated enough in your real life, to do hard work to achieve long term goals? If not, then adding time will not change your station in life.
Though wealth might be fairly easy to attain on the scale of hundreds of years - compound interest does wonders - that too assumes two things: first, that you have the patience to invest, and not touch the money for a few centuries, and second, that the economy that you do your investing in does not collapse within that time.
I suspect you'd find it much harder, in practice, to achieve those lofty goals than imagining them in the comfort of your home.
You might also be able to create alliances, but alliances usually don't trancend generations that well, as the people you made deals with age and die, and new ones, with new ambitions, personalities, and goals take over. Further, you'd be quite the target, if anyone found out you were immortal - imagine the commercial interests in getting you into a lab to be tested and disected to try and figure out what makes you tick. You would have to operate in total secrecy about your immortality, and that would mean moving around a lot, so that the people around you would not start to wonder why you don't age.
Hard to build any sort of long term alliances if you can't divulge your "gift/curse" and can't stay in one place too long.
And as I said, ultimately all this toil would come to nothing - literally - as you spend an eternity floating in nothingness, in complete sensory deprevation (as there would be nothing to see).
Maybe on the scale every hundred billion years or so, you might see a tiny flash, as an unusually large quantum fluctuation took place. Not much of an entertainment.
