I currently have an I7 4770 and a gtx 750 TI. I ran some tests and realized that I need a new GPU and realized that it is bottlenecking my 4770. I want to get one of the higher end GPUs. I was looking at getting the GTX 1070 because it is really good and I can afford it. I just don't want to buy a GPU that will be bottlenecked by my CPU. So, my question is: Will a GTX 1070 bottleneck a I7 4770? And, are there any other really good GPUs that run really good with the 4770?
