Time to settle this with some bad math!
Assuming you are properly remapped and currently have +4's.

Switching 2x +4 implants to +5

Average SP/Hour Diff
from 2610 SP/Hr => 2700 SP/Hr => Gain of 90SP/HR

SP Gain with +4's in a month: 1906563.24
SP Gain with +5's in a month: 1972306.8
=>
SP gain over 1 Month: 65743.56 SP

1 Month = ~ 730.484 hours = 1 Plex = ~$20 USD

price of 2x +5 implants: ~240mil ISK = ~$8.51 = ~313.06 hours

So where is the break even point? What should +5's cost?
So the return rate is 1/29th or (i.e: 90/2610)
==> 25 hours per month = 19.16mil ISK
240mil / 19.16mil = 12.52 Month

In other words the 2x implants would pay for themselves after 12.5 Month in the amount of time they have saved your char in training.

That's not including the time for Cybernetics 5. Or the opportunity cost of investing 240mil ISK. Or the chance of you getting blown up with them!

Side fact from above:
1906563.24 SP / 90 (SP/HR) = 21184.036 hours = ~882.667 days = ~29 Month!
==> By switching to +5 from +4s after 29 month you will have gained one month of training vs +4's.

TLDR: Really waste of ISK unless you are in it for at least a year and are not going to remap and not going to get podded.

Disclaimer: Its late and I didn't feel like double checking this.

Somebody sell this man some implants. Time has a price. Its called character bazaar.

In my opinion not worth it unless it is a highly specialized alt planned for a long time. Almost never worth it for the first char.

As others have pointed out, it is helpful to train certain long skills to V or stick to a skillset depending on your mapped attributes. However you will want to try out many skills from different categories and you will want to have them earlier, because unless you are pretty hardcore into this game, the interest will start do decline after some time and you probably won't be playing enough after the time it took you to reach the break even point. It is more fun to try out different stuff than getting 2% more efficiency in a certain area, which you probably won't even notice in practice.

You also need to consider that after years of playing it won't really matter if you have some more million SP with 5's. I am in such a situation, I play since 2008 and I am training Marauders V because I don't really know what else I could train that would really benefit me (I don't plan training for capital ships). Also, after a long time you probably only play occasionally and dont give a damn if you have some specializations to V instead of IV, generally speaking.

So I wouldn't make long plans into the future because they will never fullfill themselves as planned :)

*MY SIDES*

There is no such thing in EVE. Well, maybe shipspinning. Dock up in jita and speculate on Spreadsheets Online, if that's your thing.

Short answer: NO

Long answer: Nooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo.

Slightly more nuanced answer: Cybernetics V is good to have, +5s are a waste of your time (or money if you're buying them with PLEX money). +4s are fine for basically whatever and if you're in a situation where you might actually be podded you probably wanna stick with +3s, since they can be replaced basically instantly form pocket change.

When I Start new alts I train cybernetics 5 first and then actually start training. Thats just how I roll though. I also do a remap

I went with 5's on both my toons and don't regret it one bit.
If you want to do alot of pvp with frig's to start out join Red vs Blue since they don't pod ppl and it will let you get a feel of it.

My 1 month is coming up here pretty quickly. I have been able to pull ~2 million skillpoints since first posting this...granted I am int/mem remapped and am training industry skills so I might be closer to 2.3 mil. I think if you can pull off getting +5's this early it is absolutley worth it.
