Graphics card upgrade help

I am looking to upgrade my video card. I currently have this system I want to know what the best card I can get is for under $150 without having to get a new power supply or anything else. I'm really only looking to play like Diablo 3 on it, but I would like to play at max settings. Any help would be much appreciated. Thank you in advance. Also, this will be my first time installing a video card, how difficult is it?

  1. i Believe this one would be good it can also play many new games on high setting

    SAPPHIRE 100315L Radeon HD 6850 1GB 256-bit GDDR5 PCI Express 2.1 x16 HDCP Ready CrossFireX Support Video Card with Eyefinity - 139.99$

    it's very easy to install it, just screw out those that needed to be screwed out, and then remove the graphics card inside if it has one, if not then just open the slots on the back(it has screws on the side which i said above, then put the graphics card then screw it back in to keep it tight there and install it's latest drivers
  2. It says that I have a 480W power supply, and from reading elsewhere on the site the 6850 needs at least a 450W power supply. Am I pushing it too close?
  3. the 6850 needs at least 300watts

    the advertised wattage already has a substantial headroom.

    Do you know which brand the power supply is? Might be pushing it close for a cheap brand PSU
  5. Look on your power supply for how many amps the 12V rail/rails can supply.
  6. All I know is what the newegg prduct description tells me, I will be opening up the computer in a couple of days to clean it. Where do I look for the brand of the power supply and how many amps. Also with the new 7000's coming out will this card be getting cheaper?
  7. it should be on the powersupply unit. with a chart.

    you just have to look at the +12v(s) and how many amps it has.
  8. The 6850 is a great choice. You can also probably get a 6870 on Newegg for less than $150 with a MIR.
  9. What is the proper amount of amps that I need? And im assuming the 6870 will definitely push the power supply?
  10. It really depends on your power supply. If it's shitty one, I wouldn't let it eat the 6870. If it's a quality one, it will have no problems handling 6870. Really, post the model.
  11. you'd want more than 30 amps on the 12v minimal. and a 6870 might be pushing it if you don't have a good psu, probably need at least 35 amps.
  12. I opened up my computer and took a pic of the power supply.
  13. that will not work.
  14. It will not work for 6850 or 6870 or both? If both what is a cheap power supply that will work?
  15. Best answer
    this is a great $60 power supply that should power either card
    SeaSonic S12II 520 Bronze 520W ATX12V V2.3 / EPS 12V V2.91 80 PLUS BRONZE Certified Active PFC Power Supply
  16. that psu is so bad Im surprised your computer is running now.
  17. Dang man will that power supply work with my motherboard? And how hard is it to install a power supply
  18. Installing power supply is not a big will support your motherboard
  19. will this power supply work for those cards and my motherboard?

    Sorry for all the continuation questions you guys have been a great help so far.
  20. Alright so I am going to go with the Seasonic 520W and probably the 6870. Anything else I should know before pulling the trigger?
  21. Seasonic is a great brand. And 6870 will walk you miles at that price. Good luck!
