considering how outdated AM3+ is, the power requirements and low performance per core
it's almost impossible to justify AM3+ compared to haswell i3 for the lower end (4300/6300 with low cost MB + small OC) or comparing to locked i5 +$50 MB (8320+good MB and cooling + OC) based on cost effectiveness or performance for gaming,
Kaveri is not even worth mentioning as a CPU, and the Richland X4s seem to be clearly outperformed by i3s, only comparable to similarly priced Pentium...
if you exclude (small) cost differences there is no reason to even consider AMD...
so yes... I'm sure you can find certain situations more favorable to AMD, but overall AMD is in a really poor position, the argument you can use to defend AMD is that gaming most of the time is GPU limited, but I fail to see this as an advantage when AMD is failing to deliver a clear cost advantage or anything....
