I have recently bought an M32AD Asus with an i7 CPU GeForce GT 740 GPU. I was looking into getting a better card like the GeFroce GTX 750 Ti or the GeForce 750. First question, will these cards fit my computer and run properly? Second question, what graphics card should I get to play games such as DayZ, H1Z1, Planetside 2, and say Mortal Kombat X (Not sure the graphics card need to run MKX) Need some help on this computer before my month runs out that I can return this sucker and get a better one!
