it shouldnt. IPC is similar to the G4560 and Jayz2Cents did a video showing that bottlenecking doesnt occur until the GTX 1080TI ranges, and the 2600 has more cores and threads which helps other multitasking workloads and maybe some games that can take a bit more advantage of the extra cores/threads.

It's been said to not get the 3Gb version of the 1060(I forget why though). I don't see too much reason for either one to bottleneck the other
the 6gb version is a refresh, and has more power as well as more VRAM, making it sorta like a 1060 TI. 1280 vs 1152 cores i believe.
