What do you think of my PC?

I have a Dell Latitude E5430 non-v pro. It has 8 GIG RAM (DDR3), core i5 that is clocked at 2.67 GHz. I am using a 500GB hard drive.I love to play games but it seems like only older titles will run on it well. Should I upgrade the memory to 12 GB or should do away and get myself a gaming PC once I have enough money?
