My guess is you're playing a pirated copy that doesn't have the performance patches or some other issue that's not related to the game itself, because my rig is much worse and I can play comfortably at high at 720p at a constant 60.
Wow... Just... wow....
So because you can run the game just fine with your setup means that everyone else having a problem must be a pirate? How do explain that my copy, bought legitimately from Steam and set to auto-update on high priority whenever a patch comes out, cannot run the game without severe performance issues? Piracy has nothing to do with it mate. Performance optimizations on the other hand... See, here's the thing. When performance optimizations are done to a game, they are done for select hardware with each patch. The pool of optimized hardware grows larger with every optimization patch, but it will not cover all hardware for quite some time. Just because optimizations were done that fixed your problems, does not mean that those same optimizations were a fix-all for everyone.
As for the OP, you can only wait for Larian or Nvidia to decide to do something about this. I've been posting constructive posts regarding this issue on these forums for over a week and all I have gotten as a response is that Larian is "aware of the issue". But "aware" and "working on" are two very different attitudes in my book. I really hope the next big patch will address these issues.
Oh, and here are the readings I observed from RivaTuner on the usage of my hardware...
------------------------------------------
Core 1-
LP1 = 50-100% load
LP2 = 10-20% load
Core 2-
LP1 = 10-20% load
LP2 = 5-10% load
Core 3-
LP1 = 0-5% load
LP2 = 0-5% load
Core- 4-
LP1 = 0-5% load
LP2 = 10-30% load
Total CPU Usage - 10-20%
GPU 1 = 80-95% usage
GPU 2 = 80-95% usage
FPS = 28-34
