Dont throw me the pc part pickers because everywhere isnt usa. My country si very expensive. Gtx 1070+16g+coller+i58400 will cost me about 1500-1600 usd and gtx1060+6g+i58600k will cost me 1200$. Now the first one is not prebhiolt but the second one is and I cannot find i58600k in my country so I can buy the second prebuilt and sell the gpu and buy gtx1070 or build my own
