So, Newegg has their presidents day sale and they have the EVGA 1070 FTW edition for sale. I have a Gigabyte Z77 D3sh Motherboard, with 8gbs of 1333 mhz ram. My CPU is a Ivy bridge i5 - 3570k overclocked to 4.2 ghz. My current graphics card is a GTX 960 2gb and was thinking about upgrading to the 1070. I understand I wont encounter bottlenecks at 1080p 60fps. But I'm thinking about buying a 144hz. so will it bottleneck or should I be fine with this processor?
