Hi guys,
I made a thread a couple of months ago with a similar question but at the end of the discussion I came to the conclusion that the upgrade I was going for at the time wasn't worth it.
This time however, I am making a big upgrade instead of a small one

Current setup:
AMD 960T @3GHZ x6 Unlocked
GTX 560ti
530w beQuite PSU 80+ Bronze
8GB DDR3 1600 RAM
M5A78L/USB3 Mobo
Here are the upgrade options! Either I get a GTX 970 or an i5 Haswell CPU + Mobo. I was thinking of the i5 4690k, any motherboard suggestions?
Which one of these will be a more significant upgrade? I play lots of games and have been noticing that I need to play with lower shadow settings etc nowadays however, I'm still playing on high fine. I game at 1080p on a 60hz monitor.
Games I play >
CS:GO
Diablo 3
Guild Wars 2 (Very CPU dependent which my current CPU doesn't handle well)
I always play the latest games that come out i.e lately it's been Shadow of Mordor and Lords of the Fallen however, those 3 are my most played.
