I agree with what's been said before. Plus:
- The best bike is the one that fits you (so if you can test ride or test fit any of the bikes you are considering)
- What if you don't end up liking track? How will you feel about spending more on a bike for a sport you don't enjoy?

If you're just starting out, I would get a cheap, decent track bike that fits and that you want to ride. Then you'll have money left over for gearing, tweaking your fit, and "performance oriented upgrades" (which you don't need until you're competitively racing and losing by tenths of seconds).

Most people that ride at the track (at least at my track) won't ever be in a "the bike is holding me back" situation (myself included!).

Also, the Planet X isn't a noodle, but I'm not putting 2000+ watts into it
