I am interested in buying mortal kombat X. Unfortunately, my graphics card is not powerful enough (I have a GT 440). The minimum requirement for mkx is a gtx 560. I did a bit of research and found out I need a 2x 6 pin power connectors but my psu only has 1. I have an i5 processor and a P8H 61-M LE motherboard. My PSU is an Alpine 700W. Any suggestions on what PSU I should get and if the graphics card is compatible with my other PC specs? Thanks
