At the moment of this writing, what is, in your opinion, a cheap but generally accepted CPU and motherboard that can play most games(and at least Battlefield 4 comfortably on medium settings)? A tier below and after listing would also be appreciated. I didn't ask for GPUs because I figure the CPU is more important, but feel free to list away. Just know I'm on a tight budget and I'm looking to upgrading when I get more money. Thanks.
