I really would like to play counter strike global offensive on 144hz. Is it possible to build a rig + a monitor(144hz) at around 2500-2800rm? If not could you suggest something but not more than 3100rm.

I don't really want to play any other game at the moment and I'm perfectly fine playing at low res, low quality and at 4:3 in cs go as long as I can maintain high fps and play at 144hz. Nothing too special. Playing cs go on really optimal settings would be great. Thanks really appreciate it.
