2700k or 3770k

The 3770k will have more features available and ~10% better performance. I'd say it's worth it considering how good CPU longevity is. But are you buying used? Otherwise not 4790k? There's a sale atm and it's only 240 https://www.overclockers.co.uk/showproduct.php?prodid=CP-559-IN
Personally I dont think there is enough difference in it to bother. If you can get the full upgrade for next to nothing you might as well, but other than that... eh not worth it, you can overclock sandy WAY better than ivy and clock for clock there isnt much difference at all, pci-e 3.0 is nice but does pretty much nothing for gaming.
If you are going to "upgrade" You might as well go for devil's canyon, but even then there really isnt that much in it imo...

i have the same board running 2 970's and i have run a 2550k@5ghz, [email protected] and [email protected]. the 2600K is the fastest so far.
It will be at 4.8ghz,clock it to 4.6ghz and the 3770k will be quicker,pretty sure pcie3 will help in xfire and sli aswell
SB generally clock better than Ivy unless you delid, hence the difference in overclock so there probably is no chance of getting it to 4.8Ghz. Also from my own experience the difference when they are at the same clock speed was between 3%-10% and this is for stuff like encoding to winrar etc, but for gaming the difference was negligible, and as he was gaming then it's simply not worth it.
He's got a Z77 mobo which supports second and third gen only. No point in getting a 4790K and new motherboard.
As of a few years ago PCIe 3 made less than 10% FPS difference compared to 2. (And most of that was probably the better efficiency of Ivybridge.)

IMO - if the 3770k is 10% more then go for it, otherwise no.
Really though, I'd expect your 4.5 GHz 2500K to be fine most of the time. Hyperthreading only makes things a bit smoother in some games during some scenes.
Depends if your going to overclock. That 10% performance improvement quoted above is a best case scenario - its more like 5% difference.
If your overclocking the 2700K will give you better performance, sandybridge was awesome (and still is tbh!) - ever since then its been slight improvements in IPC but at a cost of poorer overclocking.

the pcie 3 did not make a difference with my 970 sli at 1440 or 4k.
delidding only helps if the chip is being thermally limited in the first place. my 3770K was delidded with CL Pro and the temps were good, but it was still not great at overclocking.
which cpu to get should purely depend on which can overclock higher. if the sandy can do 200mhz+ more than the ivy it will be faster.

Exactly, and generally SB overclocked better than Ivy so it should be a no-brainer as which one to go for.
4.1 is quite "meh" for Sandy on an ok cooler even - you should be able to get 4.4+ on most chips easily
If folks knew what they were doing, had a good cooler (like a D14) and a decent motherboard (preferably Asus), then generally poor overclocking ones would do ~4.5Ghz and less, average/decent overclocking would be ~4.7/4.8Ghz and golden would do 5Ghz.
General rules of thumb are to keep temps below 80c under real load (not synthetic like Prime95 etc I don't recommend it) voltage under 1.4v. Also use the offset method to overclock. Though I had a 2600k that ran 5Ghz using 1.42v max using offset method but load temps were in the 70's using a Noctua D14. I've known people run up to 1.45v (offset method again) for years with no degradation, just kept it in the 70's load temp wise.
