Guild Wars 2

So I have an Ivy Bridge processor (yes, still a bit old, but only ~20-25% slower than a 6700K. I have a 3770K at stock speeds) and a GTX 1070 (I upgraded recently for some of the more graphically intense games I play). However, when I went from a 660Ti to the 1070 (the 660Ti was also having issues with Guild Wars 2, but I was consistently getting 70-90 FPS on ultra settings, even in LA) my framerates dropped considerably.

Now on low-medium settings I’m lucky to get 60 FPS in LA, and at world bosses even less. What happened? Is my processor holding me back now? Do I need to upgrade? I wasn’t planning to upgrade for at least a few months until Cannonlake/Zen come out, so…. what happened?

Upgrading the GPU shouldn’t cause your FPS to drop even though the CPU could be a bottleneck. They would simply remain the same in that case. But an i7 3770k shouldn’t be a significant bottleneck for a 1070 anyway. Did you update to the latest drivers from nVidia?
