  1. Exactly what model?
    What are you doing/want to do with the system?
    AFAIK all the new systems need at least a 24 pin for the MB plus 4 pin for the CPU, I'm not calling you a liar, but please confirm the wiring configuration.

    Given the limited power, I'd say the DDR3 HD4650 is as much as I would want to install-but it's a weak card for games and if you want or need more graphical clout, you'll need to install a bigger PSU.
    For HTPC use the 3450 might do, if not the HD4550 has good Hd/DVD decode.
  2. After a little more thought, I'm inclined to agree with Invisik.
    But, do not look for the GDDR4 version of the HD4670, that would, I think be just that little bit too much.

    A look on the Gateway site shows the PSU as looking to be standard ATX format, so a replacement should be easy enough.

    But what do you want to do with it? Even the HD4670 is quite weak for gaming, and, frankly far too much for even HD replay.
