Pros: Price for performance, OC'ing if needed
Cons: the feeling of wanting more..?
For me this upgrade was pretty big. I went from a Phenom II X3 720 (rushed buy do to burning up old CPU) stock to the 4100, which I plan to OC today when my cooling arrives. Paired with the 990fx seems to be a great matchup. I dont have any marked numbers to post as if I was solidifying my ranking but again AMD comes through in the price/performance platform. A friend of mine got the 6100 and we will both be OC'ing so hopefully I can put up some similar numbers.
