So im trying to upgrade my gaming setup. My current computer was purchased on a tight budget kind of out of an emergency so its not the best. Its an asus with an AMD A4 cpu. I just bought an EVGA geforce gtx 950 the overclocked one. Im not noticing much of a difference from my old gpu which is 4 years old. The games im playing are Diablo 3 and WoW. My question is could this cheap of a cpu be causing me to not see a difference? is it bottlenecking my games? should I upgrade my cpu which would require a new mobo? should i try exchanging the card first? If i upgrade can i go to a AM3+ and not do a complete clean install?
