Conclusion

Which are the better chips to buy considering there really is not much in it from a financial view?

AMD's move to second-generation Ryzen chips has brought more performance and keener pricing to the mainstream CPU market, and that can only be considered a good thing. It's worth repeating that you cannot buy a bad processor these days, so the only choice is which one to go for.

The non-X chips are basically the same processors as the higher-performing X line but rein in frequency and voltage in order to hit a 65W TDP. The upshot of such an approach is multi-threaded performance drops by close to 15 per cent and 10 per cent for the Ryzen 7 2700 and Ryzen 5 2600, respectively, but they still remain very capable mainstream chips.

If performance is more important than energy efficiency, a couple of minutes spent in an overclocking program will yield solid results, generally matching the X parts, so how do we sum it all up? Which are the better chips to buy considering there really is not much in it from a financial view?

The answer is that, in our mind, it's worth going for these 65W models if using a smaller-form-factor PC with limited airflow. That, or if you really want to run a quiet PC that still has decent performance. As enthusiasts, we'd naturally gravitate towards the X-designated parts for guaranteed performance, but the non-Xs remain solid choices, even if the value argument isn't as strong as first-generation models.

 

The Good
 
The Bad
Solid value
Impressive multi-core performance
Unlocked
Lower TDP handy for SFF PCs
 
Single-thread is better but not great
Limited all-core overclocking headroom

The Ryzen 5 2600X is not worth the extra cost over the Ryzen 5 2600 since the price difference is enough to get a better cooler anyway. However,the Ryzen 7 2700X is worth it over the Ryzen 7 2700 for a normal sized system as the cooler is better and probably worth the extra money.
Good for the supposed TDP cap, but doesn't seem to be that much more efficient in the real world. I was expecting much better things from precision boost 2 - manual overclocking shouldn't give a noticeable increase, but perhaps the TDP cap is limiting it. Is there a way to increase the TDP cap and then letting PB2 do its thing?

should happen in AMDs new overdrive but I don't think it's currently implemented.
Yup, didn't see it in the options. Waiting for support.

Most reviews found manual overclocking didn't do much for the X series parts and sometimes peformance was worse,so its definitely fine for the X series parts to the extent overclocking currently is not worth it:

The main issue is apparently Precision Boost Overdrive is not properly implemented,so there might be additional gains to be made.

However,most reviews for the non-X parts show decent gains from manual overclocking,so I assume the CPUs are hitting the TDP wall as the 2700X has a 105W TDP for example - power consumption seems to be around 20W to 30W better for the non-X parts looking at multiple reviews.
