Ok to Crossfire?

My birthday is coming up soon and I was wondering if I would be able to upgrade my 7850 to a crossfire 7850 setup for increase performance on all games.

I just need to make sure my computer can handle it/ if it would be a good idea!

CPU - i7 2600 @ 3.4ghz
GPU - MSI TF3 7850 OC
PSU - Antec BP550
MOBO - ASUS P8H67-M PRO
RAM - 8GB DDR3

Ask for any additional information if needed.

  1. You overclock CPU/GPU? How many HDDs/SSDs do you have?

    Even if you don't overclock and don't have many HDDs/SSDs I'd say no.
  2. The ANTEC will run it but 600watts would have been better.
  3. according to http://www.gpureview.com/show_cards.php?card1=678&card2= the 7850 uses 130w of power and 2 would be 260 so i would say no upgrade the psu to a corsair tx750 or any thing above 700w of power
  4. Well, the basic power Antec model isn't superb, but those cards are pretty efficient so I do believe that your PC could handle it. It would not make ME very comfortable, as I like to have my macchine operating in the sweet spot of efficiency of 40-60% capacity. Also you do not mention overclocking, which is also why I choose to have quite a bit of headroom.

    If it were me and I wanted to get the most performance out of my computer, including overclocking and running the top software titles maxed out, I would invest in a better power supply of at least 650Watts. I use a 750W PSU with a single HD 6950, but I overclock and have a heavily modded machine with many fans , lights, etc.

    You could however go ahead and order the second card and save towards a PSU, but i've given you my best recommendation.
  5. I only overclock my GPU, nothing else.

    What PSU should I buy instead on a budget?
  6. Would I be better off selling my ALMOST new 7850 and putting the money towards something better such as a GTX680?

    Would my rig be able to use a 680 at it's full capacity?
  7. I would say GTX670 if going single card.
  8. What about a single card on a >$400 budget that I woulnd't have to change any parts of my rig?

    You can always use a GPU/CPU at its full capacity regardless of what its mated with. Servers didn't suddenly get slower because they only have a built in 8MB video card.

    If you want pure performance and 3D goodness , go with the 670, 680, or 7970
  10. ill buy your 7850, 140 w/shipping...

    Odd no one mentioned anything about the mobo:

    Good catch but it supports crossfire although the second slot is at X4 speed http://www.asus.com/Motherboards/Intel_Socket_1155/P8H67M_PRO/#specifications
