I just recently upgraded my Video Card from a GTX 750 Ti to the GTX 970 FTW and noticed a huge performance increase. I also am installing more RAM but have been trying to decide on whether or not I should get a better CPU. My current CPU is an FX-6300 (six-core at 3.5 GHz), with today's standards in gaming performance, should I upgrade my CPU or should I stick with the six-core and focus on just installing more RAM along with my new GPU?
