The reason for an upgrade has to be good. The list of positives on this machine made the choice easy.
I up graded from a T5810 for the better chip, easy HD removal on the T5810 and also the more hd's bays as well. I have also gone from 32gb to 64gb ram and have a much better quadro card. It has more pcie slots and windows 11 pro. The computer came in mint condition and will last as dell make great workstations.
