Bad performance with Premiere CC...

Computer specs:

CPU: i7 3820

Memory: Corsair 16 GB

GPU: Gigabyte Windforce 780ti

SSD and HDD with Adobe installed on SSD

Anyways, I was using CS6 prior to upgrading to CC and at the time, I had a GTX 670 GPU installed. I then upgraded my Adobe to CC and GPU to a 780ti and noticed that the interface with Premiere is really choppy. When I'm maximizing and minimizing the timeline it looks like my computer is struggling to do so. If I'm dragging files onto my timeline from folders, it's also really choppy. I opened my Task Manager and nothing is hogging my resources. I also have the Mercury Playback Engine enabled. I'm only editing 1080p footage and don't know why there's a performance issue when there shouldn't be.

Any ideas?
