Greetings! I have a Lenovo Z51 laptop. It has an Intel core i5 5200 @ 2.20 GHz, boosting up to a max of 2.7 with Intel's speed boost tech, 4 GB of RAM (which I was planning on upgrading to 8), Intel HD Graphics 5500 AND a AMD Radeon R7 M360 dedicated graphics card. I was just wondering if this computer is a good gaming computer or if I should consider buying a better system. Thank you for the feedback
