I've got a i7-3770 3.4ghz, MSI B75MA-P45, 2x4 GB ddr3 ram and a 620W PSU in my current PC.
Will i be worth it performance wise?
And/or will it bottleneck?
In certain games you could get a bottleneck from the CPU, but in the majority of games the 1060 will be very beneficial. The 1060 is roughly double the performance.
