Okay I am currently planning on upgrading my Alienware x51 R2. I currently have an intel core i3-4150 and a GPU which is a geforce gtx 745 with 8gb ram... yet when I try playing games like H1Z1 In medium settings im getting 10-15 frames a second I have to play it in VERY low just to reach 30 frames... If anyone knows if theres a way to "unlock" my alienwares gaming power I would like to know. But thats not the questions my question is should I upgrade my cpu to an intel core I7 or a Geforce GTX 960... I know having both can damage my computer because of wattage power but I just need to know which upgrade will improve my gaming performance more dramatically
