I ordered a Athlon II X2 250 to upgrade my chess box, which has the M4A77D motherboard. This CPU is faster then the old Athlon X2 4200+ for the same power consumption.
Price rot has this CPU down to US $16 which from its original $87 some 5 years ago, its not the fastest but for my needs its plenty
I am not sure if this CPU can support 4 sticks of RAM on a AM3+ motherboard, I do not care if the RAM speed is lower, as long as it works
the cheapest AM3 boards have 2 slots, but I like boards with 2 memory slots so that larger amounts of RAM can be installed for more demanding workloads
AM3+ boards are still a few more pesos but there are lots of options out there, this cheap CPU was selected for its flexibility and its low power consumption
