The only real reason i was going 1500x was because i was going for a budget of around 600 of new parts from newegg. So really i would be game for the 1700x is the price is good. As for the board and memory. Again, price dictates it. I could buy exact parts if i bought new but it also means giving in some areas. Gimme a few to look at some costs and ill shoot you a pm.
