Hi! I am completely new to all of this so bare with me. I want to upgrade my computer's graphics card but having trouble understanding what to buy. I'm currently using a nvidia quadro fx 3450/4000 SDI. So apparently it is a PCI-E x16 and i've looked online and most of them state that are PCI-e 2.0, 2.1 , 3.0. So are any of the follow going to be compatiable to replace my Nvidia Quadro ? And the label on my power supply states that it has a MAX of 375W.
