I am wondering how much more MMO gaming performance I can get from upgrading my current desktop system without replacing the CPU and motherboard. Specs are as follows: AMD FX 6300, Gigabyte GA-990FXA-UD3, 8GB ddr3 generic, 530w psu, GeForce gtx 970. Would getting more/better memory give my system a noticeable boost, or should I just save money to do a full CPU/mobo/memory upgrade later? Thanks!
