3 months ago I posted about upgrading my X51 R2. I got back into PC Master Race gaming and have been playing Rust. I have no doubt my prior build would never even been able to open Rust. I am able to run it on potato but I want to attempt to run it at a higher quality. I currently get about 30fps on potato. My next two potential upgrades is the HDD to an SSD OR GPU. For running Rust on higher settings with an i5 Quad and 16GB RAM would you suggest SSD upgrade or GPU? Current Build: NVIDIA GeForce GTX 745 INTEL(R) CORE(TM) i5- 4430 CPU @ 3.00GHZ 16GB DDR3 RAM Thanks!!!
