Should I crossfire 4850 1gb x2 or get the 7850?

Should I crossfire Radeon HD 4850 1gb x2 or get the Radeon HD 7850?
I already have one 4850 installed and I have an open PCI-e slot.

More about should crossfire 4850 7850
  1. short answer-if you can afford then go with 7850.
    ask if you need explanation.
  2. if you have the sufficient psu, the 4850 would be the monetary decision, but in the long run, having 2 cards will limit your upgrade path.

    How would having 2 cards limit my upgrade path? :O

    if possible, there may be a point in which you have 2 4850, and the next monetary decision after that would be a 3rd one, which will be heavy on the psu(going to assume you may need a new psu and mobo) if detail in games magically skyrocket, whereas if you have a 7850, you get to the point where can either use another 7850 or upgrade.

  7. I understand now. Thank You very much.
  8. What kind of power supply would you recommend? I'm having trouble finding one. I know I need a 750W but I don't know the difference between mulitrail and single rail.

    1-4850 CF will consume more power
    2-will produce more heat
    3-more noise
    4-more issues
    5-7850 is a better performer.
    it has newer technology,drivers,less heat,power consumption,noise and issues.
    bottom line-
    7850 or if you can afford 7870 would be my choice.

  11. I know this is solved but I just upgraded a 4850 HD CF setup to a single Sapphire 7850 OC card. These were the benefits I saw:

    Probably Double Frame-rate using same settings
    (CF only really got me 20% increase in FPS with lots of instability problems. I think DX9 CF isn't terribly well supported)
    Use of DX11 drivers instead of being limited to DX9.
    Something like 70% reduction in power consuption
    Much Quieter
    Runs cooler and doesn't cook me during long game sessions
    2GB VRAM vs Double 512MB VRAM means big textures and 1920x1080 no longer an issue

    The two 4850's will probably sell for ~$50 each, meaning this was a nice $150 upgrade. On my Core2Duo E7200 @ 3.2Ghz it's about I'll ever need to game at 1080 until it's time to upgrade the MB/CPU/RAM next year.


    Hope that helps anyone else who runs into this thread. The 4850 was really a good investment. I was surprised how long it took for a mid range card to be a not insignificant upgrade.
