I was mostly suggesting the 1030 on the assumption that OP would buy another board with a 2600k or buy the board you were suggesting - in which, the 1030 would surely work. If he buys his i5-7400, then a 1030 would work there as well.

also I'm puzzled on the gpu situation in the OP's country. My country is poor, Philippines. Over here, some low budget computer shops have a dozen or so old pc's equipped with GTX 750ti, GTX 460, or GT 1030. Because these three gpu's are enough for CSGO and DOTA, which some kids pay coins to play for an hour or so. I'm wondering why the OP is having a hard time obtaining even a GT 1030 or any old gpu of similar strength. Which is why I asked how much a GT 1030 is in his country.
