Build yourself a new gaming rig. Plenty of videos on you tube and for 4 or 5 hundred quid you can get a decent little set up. Easily play bf1 and things like counterstrike at 60 fps. Maybe won't be ultra graphics but easily run high. With the new graphics cards being released the older generation are becoming a lot cheaper. New motherboard, 16gb ddr3 ram and an i7 chip. Easily under the 500 quid mark.
