I am upgrading my stock dell workstation 490 to a new graphics card, but before I buy it, I want to make sure it will work with your help. I have a 750w power supply and my motherboard is a Foxxconn LS-36, also my current graphics card is a FireGL v7200.
If the PCIe X16 slot on the board is version 1.x then there might be a no video issue with ver 2.1 card like the 6570. That issue only applies to 2.1 cards no issue with 2.0 or 3.0 cards or if the slot is version 2.0 or newer.
It does mean that there is a chance that the card will not work in that motherboard, if it works it is an entry level gaming card and should allow some gaming. If you can find a HD7750 it is a stronger card about the same power consumption and does not have the no video issue in older slots.
