So PC question time right now I play on a dell laptop with integrated graphics. It has a 6600u which has a PassMark score of 4786. I have 500$ and was thinking about buying an OptiPlex for $130 with an i5 2400 with a PassMark score of 5861. then i would throw a gtx 1070 in that, and then use that until summer job time when i would get new pc and use the 1070 in it. Is this worth it (for Arma, i can run BF1 and other games on Xbone) or is the CPU to old and I should just keep my 6600u with integrated graphics until summertime?
