Suztera :
Well the R7 240 isn't that much of a graphical boost compared to the A8 7600 integrated graphics. What games are you going to play though?
assassin's creed syndicate ,battfield,dishounred,fifa ,far cry(basically stealth games)..
Also having a 16gb 1600 mhz normal ram ,will this give the same performance as Hyper x 8 gb 2133 mhz?
