Hello, I just recently purchased a new Dell Inspiron 3847 desktop from Staples (got a good deal), and am hoping to turn it into a decent gaming computer. I am more than pleased with all of the system's specs (hence why I bought it) except for the intel integrated hd 4600 graphics just isn't going to cut it. The PSU is only 300watts, so I definitely am planning to upgrade to 500watts. All I need to know is which graphics card would give me the best value, and allow me to play games (ARMA, Day-Z, Skyrim, sports games) at pretty high settings with good fps. For the PSU and GPU I would like to keep it under $200, however if you think it is necessary to spend a little more to get the best bang for my buck I will definitely considering going above the price range. This is my first gaming pc so I have little knowledge about this, which is why I am asking. Thanks in advance!
