The City of Sinners and Winners: New Vegas

Ok, so I just recovered the platinum chip and I was about to bring it to Mr. House. But I asked myself what my options were, and while I know who they are with, I do not know what they lead to. So, without any spoilers preferably, who can I bring the platinum chip to and what is the general, "spoiler-free" outcome? (I'm not to keen on giving such a thing to Caesar's Legion either, as they crucify people and it doesn't seem like a good idea to turn them into the head honcho's.)

Im not sure what any of the outcomes are but i chose to listen to Yes Man. Caesars Legion seemed corrupt and not very good people to be in control and Mr.House I didn't really like , so I just disabled him.

Well, I did pick House at first, but after his demonstration I was afraid of my choice. So now I'm juggling between NCR and BoS, but I want to know if there are other options, and I don't want to pick me.

Also, where can you find *real* hookers; not sexbots anf ghouls... UGH...
