I currently have a ~2 year old computer, and am looking to increase performance while gaming but not sure how to go about it. Current specs:

GTX 980 Strix
DDR3 2400MHz (Not sure if running at 2400MHz) 4x4GB
1TB SSD
Maximus VII Mobo (1150 Socket)
i7 4790k
H105i CPU Cooler
EVGA 1000W PSU (80+ Platinum)

For a general idea, I play Rust a lot and have a 144Hz monitor and want to get around 144 FPS with decent settings. Now, don't get me wrong, Rust isn't currently that well optimized but anything helps. Thanks!
