Help for choosing a good lens for 550D

Hello fellow 550d users and POTN-members. I have a problem and want some opinions

was thinking to buy 5d3 with 24-105l kit, but thinking that budget is going wayyyyy too tight, and I dont like that.

I bought a new GPU for comp yesterday. Evga GTX 670 FTW. And I would also like to buy a new monitor Dell 27" with 2560 x 1440 resolution http://www.tftcentral.​co.uk/reviews/dell_u27​13hm.htm

So if I buy that new monitor, then having a money to buy one of these:
EF 16-35mm F2,8L II USM (used with full warranty)
or EF 35mm F1,4 L USM or EF 50mm F1,2 L USM

And if going this route, then I could buy 5d3 next May.

Opinions?
Thanks

EDIT: I just bought that monitor as well ... so now want some opinion about for the lens

2nd EDIT: if buying a fast prime like 50 F1,2L USM now, then 17-40L later with 5d3? what do You think?

What do you shoot? Landscapes get 16-35 or 17-40. Portraits get 35mm 1.4 or 50mm 1.2

Well mostly landscapes and portraits. For portraits I like my 70-200, but I really wanna check that 50 1,2L. And that would be also for low light club concerts.

So before getting FF, my 15-85 can do the landscapes, plus being all around lens.

whats the point of buying the 16-35? you will be overlapping your 15-85 and honestly im not sure you'd see a big improvement over it.

i'd get a prime instead. 35L

Mike.. havent said that I will buy 16-35L. Was just a thought, asking about it. And thinking the "future" when going to FF. Then I cant use 15-85 anymore. But like I said here before that 1st choise would be fast prime.
