So I have a Lenovo think centre with I5 6400 and 8gb ram. I want to take that cpu ram and put it In new case with new pcu and Rx 570 8gb. But my question is the it worth I5 6400 is old cpu and lga1151 only supports 6 and 7 gen CPUs I did found a used z270 Mobo for 50e but what do you think and maybe it is better to go with am4 but idk
