So, I found this CPU at a website and it was very cheap.
Its milion times better than the one I have now.
CPU's name is AMD Athlon II X2 340.
I also found a socket FM2 motherboard for him because it says that the CPU has the socket FM2:
CPU - AMD Athlon II X2 340 ( http://prntscr.com/3xgtel )
Mother Board - ECS A55F2-M3 ( http://prntscr.com/3xgtzn )
But, one guy that I contacted to help me about components compatibility says that this CPU requires a AM3 socket motherboard.
I'm confused.
