No you won't lose performance. There will be a bottleneck for sure. I am just saying this when you upgrade your computer you can just upgrade your CPU and the RX 470 will use it's full strength. It won't be useless. I don't know what Cdog is saying. I would upgrade your CPU to something like a 860K or go with an i3 4130. You would have to get a new motherboard though. If you don't want to spend too much time upgrading then the 1050 or 1050ti would be a good option. I am thinking about the future. Cdog is thinking about now
