Is Sapphire r7 260x 2gb oc an overkill for playing latest (as well as older games) at 1366x768 resolution? Will Hd 7770/7790 do? As for the cpu, should i go with fx6300 or Fx 8320.Or will I be better off with an i5 4570 with its integrated hd 4600? I'm really confused. I'll be using my old monitor, hdd. odd, keyboard, mouse and pc case(atx). I'm from India and my buget is around Rs 25000( ~400 USD).
