Upgrading the Graphics Card for an HP Pavilion p7-1423w

Well, I'm looking into getting of this "Intel HD Graphics" mess and to a real card, but I'm not sure what all I'd need to upgrade as I believe I'd need a new power supply and such? I have an HP p7-1423w. Also, any suggestions for cards? Thanks! (If you need all my specs, I'll list them!)

  1. Oh yea def a PSU. only comes with a 300 Watt PSU. After that its a matter of if the video card will fit in your case. some of the bigger cards may not fit in this case you have. So you may want to measure from the Back bracker (Where it screws into the case) to the front where the card drive is but take off at LEAST half a inch to plug the power cable in (Some have the power plug on the back)

    Otherwise go ahead and get what card you want. It also support all 2nd and 3rd gen CPU"s as well.
  2. your system only comes with a 300W PSU; therefore, you are limited on which video card to add without upgrading the PSU to a good 450W+.

    using the PSU you have now, look for video cards that don't require additional power from the PSU (no 6-PIN connector). ATI Radeon 5000 series
  3. Best answer
    The best graphics card you can install with a 300w PSU is either the Radeon HD 7750 or the GTX 650. The GTX 650 a little more powerful (by 8% ??), but since they are lots of rebates for Radeon HD 7750 card flying around, I have seen a HD 7750 1GB DDR5 card selling for as low as $65 - $70.

    These are mainstream cards. Much better than the Intel HD 4000, but they will not let you max out graphics on a 1080p monitor unless of course it's an older game with relatively lower requirements than current games. At best I think you can get good performance for most games using medium quality graphics at 1080p resolution.

    Your budget will determine what you can upgrade to.
