I'm saying your expectations might be too high for your system. Just because you upgraded doesn't mean you can get 144fps in every game, VR is extremely performance heavy. Here's someone with your same GPU that settles for 90fps on low settings in Squadrons after a lot of testing:

That said make sure your GPU is set to prefer maximum performance, and after that you can overclock it for a bit more performance but there isn't much you can do without giving up something. Get FPSVR so that you can easily tell what is bottle necking your performance, it will almost always be your GPU but it's good to be aware, then you can turn down some settings to get your desired frame rate.
