We know you have asked this question before but it is not possible to answer. I think AMD make the best motherboards but Intel make the best CPU's so we have an immediate incompatibility issue. You need to give us a chance by at least picking a motherboard , or CPU, to build a system around.
Also what do you want to do with the PC, you mention gaming, but what sort. If internet based you will want better Ethernet capability and so the questions go on.
