Trying to Upgrade my GPU

I have a Dell Studio XPS, it is about two years old and I am trying to upgrade the GPU to handle newer games coming out. Here are the specs--

Dell Studio XPS 435MT
Windows 7 64 bit
Intel Core Quad i7 2.8ghz
8 gb ram (probably upgrading to 12gb or 16gb though)
Radeon 4850 HD
750gb HD
my Dell service tag is 51LNNK1
I think the PS is only 300 watt this is the model # PS-5361-2 ; which I am sure is going to be a problem.

The computer runs great but recently the video card has been overheating and it causes my PC to automatically turn off especially in heated moments of battle. I want another tier 1 video card preferably one I could play games on higher settings. Games I play are Battlefield 2, 3 when it comes out, Team Fortress 2, Call of Duty Black Ops, Starcraft 2, World of Warcraft. Most games run well on medium-high settings but the Ultra Settings would be great. I can spend 150-400 but prefer to keep it around 300. It would be awesome if the card ran quiet too because the Radeon 4850 HD is so loud when I play games or watch HD videos.

Any Suggestions on how I should go about upgrading the last Dell I will every buy?

  1. You should buy something like this one.

    HD 6950 - 270$

    Also, you need another PSU :
    500 Watt or greater power supply with two 75W 6-pin PCI Express® power connectors recommended

    For your new PSU,
    - 2 connectors PCI-E with 75W
    - 500W or +
    - Active PFC

    Like this one : Seasonic SS-560KM
    this one, CORSAIR Gaming Series GS600 600W
  2. If it's only a Dell 300watt PSU then the 4850 probably isn't getting enough power.

    Unless you have lots and lots of Windows/Applications open then theirs no need for more than 8GB of RAM.

    Either a GTX560ti or a 6950 will fit in your $300 budget but you could get a GTX570 if you really wanted to stretch it to the full $400.The GTX570 can be had for $280 after MIR and it's probably your best performance per cost ratio you can get.With either choice your going to need a new PSU.The PSU that eleclerc suggested is good but it's a bit pricey and doesn't have enough wattage for future upgrades.

    Antec 750watt
  3. Also, there are the XFX 650W core edition and XFX 750W core edition. They both provide great/stable power at a very good price.
  4. Well whats you Budegt
    iand we can narrow it down
  5. OP's budget is around $300 but $400 is possible it just needs to be justifiable.
  6. my suggestion :

    XFX 750W core edition costs about 80$ with rebates
    1 X GTX 570 300-320$

    400$ total


    XFX 750W core edition costs about 80$ with rebates
    1 X Ati 6950 2gb 250-280$

  7. Thanks everyone I am gonna look into everything suggested, appreciate the help :bounce:
  8. 6950 looks like the winner.
