***Help Please*** Old build, what should I upgrade?

[TooFarBeyond]

I was wondering what I should upgrade first for my old gaming pc. My main questions are 1) Is my processor good/will I get good performance if I just upgrade my gpu? 2) If I upgrade my GPU what GPU should I get? 1060,1070?

My budget is around 500$ and I was planning to buy something on cyber monday If I can get a good deal.

My specs are

Asus P8Z77-V LK
Intel Core I7 3770 non K
Coolermaster hyper 212 Evo
EVGA GTX 660 SC 2 GB
16GB Corsair Vengeance RAM 1600mhz
Samsung 840 EVO 128gb
WD Caviar Black 2TB 7200RPM
EVGA 650W Semi Modular Bronze Power Supply
CM Storm Case

1060 would be a decent fit , otherwise jump to a new platform.

With a 1060 would my 3770 work well? also when would I need to jump to a new platform if I upgraded to a 1060? would it be more worth to just save up for a new platform and transfer the parts from my old pc?

1060 would pair well with your current setup , but I would eventually jump to a new platform.
