[SOLVED] Is my gpu bottlenecked?

Solution
What is GPU usage and CPU usage in the games you play with vsync disabled? If CPU usage is significantly higher than GPU usage you have a CPU bottleneck more than likely.

Going from a 4570 to a 4690 is hardly an upgrade at all. A 4770 would be a decent upgrade from a 4570. I doubt a 4770 would bottleneck a RX 480 in pretty much anything at 1080p or higher.

Solution
I don't think the i5-4570 should be holding you back....or if it is....not much.
I would look at the CPU and GPU usages in a demanding game.
I think this will give you a better idea.
I don't think going to an i7-4770 with your current GPU is going to get you much as far as fps.
