I decided to take the plunge since I'm was an avid GoW player back when I had my Xbox 360 (and $30 isn't a asking price).
My specs:
i5 4670K @ 4.5 GHz
290X @ 1150/1400
1080p/122Hz Resolution
8 GB RAM
The 'occasional' hitching is pretty annoying but the games seems to be running over 60 fps in 1080p. I tried to play the game with my Xbone controller but it felt sluggish to me (I have been messing with the steam controller for the last few weeks). So I decided to change my Steam controller's desktop configuration to Mouse and Keyboard (WASD) and remap the in-game controls.
Holy shit. This franchise shines with mouse and keyboard controls. Way faster camera movement, I can roadie run without taking my thumb off of the track pad. It's a great way to play the game again after all these years
