I got double socket supermicro mainboard with xeon E5 2640 v3 ( FCLGA 2011, 2,6- 3,4ghz turbo, 8core/16 thread) that will be my workstation. I have option of buying a second cpu for a low price. Is it going to be a good option of buying it or it will not going to stand 1440p or 4k gaming in the future (when there are going to be better gpus than rtx, etc)?
