SKELETONWAR
I am not professional, but would recommend some part as cheapest on market cost vs performance (in gaming)
CPU -
70$ - Intel Pentium G3258
it is unlocked, very low power needed and when u overclock it is almost 4690k in gaming (search on Youtube will see)
Mobo -
110$ - Asus H97-PLUS
this board has M.2 SSD support SATA 6GB and it has latest H97 chipset which already allow to overclock unlocked CPU-s and u do not need Z97 or Z87 expensive ones
GPU -
240$ - GeForce GTX 760 OC 2GB
this is 256bit 2GB one of best budget gpu right now or u can get cheaper
GPU -
190$ - GeForce GTX 660 OC 2GB
this one also not bad, it has 192bit interface but steel good card for budget, but I recommend buy 760
Cooler -
25$ - Cooler Master Hyper T4
just to know G3258 support DDR3 1333 and no point to buy 1600Mhz memory (pick Kingston or Crucial do not know), also some normal PSU (also do not know which). and SSD, I prefer Samsung or Intel....overall it is much cheaper and I think u can play most games with high settings up to 60fps
