Question What's holding me back?

[Thorstwin]

I am looking for some insight on a confusing issue that I am having. My current system build is the slightly aging:
I5-2500K (Not Overclocked)
Asus P8P67 Motherboard
12 GB Ram and until recently a GTX 1060 3GB video card.

A friend of mine upgraded his video card to a GTX 2080 and made me a great deal on his old GTX 1070ti. I bought it and installed it and then started re-running any games that had internal benchmarks. (Shadow of the Tomb Raider, Far Cry 5) In most cases I am seeing just a few frames per second improvement with the 1070ti. I expected a much bigger jump in performance.

Is it my processor that is holding me back at this point? I am planning to build a new system once AMD announces their 3rd gen Ryzen chips and I can then make an educated decision between those and the new Intel chips, but I thought this would be a good stop gap in the meantime and I am just a little stumped as to these results.

Any thoughts or insights would be appreciated.

or wait for a deal on a 3770k

Thanks everyone for the awesome comments. For the record I am running 2 4Gb and 2 2GB sticks of memory, so yes, I am running dual channel.

I have played around a little bit with overclocking my rig, but have never been able to get it to go much above 3.7GHz. Even then I had some stability issues so I generally just tend to leave it at stock where it seems to be stable.

I am planning to buy a new setup here in the very near future, I am really anxious to see what AMD brings to the table next week. To be honest, even with the 1070 ti being held back by my processor and stuff, I can still play most everything that I want pretty decently, so I will just hold out till the new Ryzen 3000s or if I don't like what they have to offer then I will look into the 9th gens from Intel.

Thanks again to everyone.
