I'm going to be honest here... your cpu is going to bottleneck most modern cards imo. My old 4790k actually bottlenecked my 1060 6gb...I saw significant gains when I upgraded to my 5950x and used the same 1060 6gb with it, it was a bit surprising considering how 'well regarded' the 4790k is/was..
Only thing is, the OP has a GTX 570 and that's slower than even a 1050, so while it'll be bottlenecked, I think most games will still show big gains.
