Sounds like bad management to me.. i dont know the setup of your team or w/e but if the system was too slow for you, chances are its slow for someone else? And chances are they were b1tching long b4 you got your new system with two 22" crt's..
Sounds sorta selfish if u ask me - employee critique
Looking back at your post, you weren't meant for the management work..
Your solution was to get another pc & some big monitors, when u could've bought more pc's for ur staff to help distribute the workload.. SICK!!
