  1. What are you using it for?

    Generally, it's not the best idea to buy a graphics card specifically for a PPU... the benefits are there, but they're not substantial. If you have a card from a previous build though, then why not?
  2. Best answer
    if your buying another card, i would just get the same as what you have an add it to your multi-card array.
    You'd get more benefit from that, then you would from a dedicated PPU.
    Besides, i'm not sure an Nvidia card and an ATI card play nice anymore on the same mobo.
  3. How would I tri-fire hd5850's and do they need to be the same brand, also will three cards shoe up in ccc?
  4. Any 3 5850s will do and they will show up as three cards in ccc.
  5. 2xHD5850 are great.
    So, 3xHD5850 are more greater than that... :D

    Just make sure your PSU can handle those bad boys...
  6. it might be more powerful to sell the 5850s and get something like 2 or 3 GTX 460's/470's because SLI scales so much better than CrossfireX. Of course, only if your mobo can handle it.
  7. Well first things first, I'll need to replace my power supply, I have a 750 watt seasonic, and I guess I'll need a 900-1000watt?
  8. I don't know why others are hating on the Phsyx card idea. Go get an 9800GT for physx and you won't regret it.

    Umm. no.
    2 GTX460s is the limit and will perform worse than the dual 5850s, and consume more power.
    3 GTX 470s will cost him ~$500, while requiring a 900W+ PSU, and making his hot like an oven. Besides Crosshair Mobos cant SLI ion the first place, (the hack does work, but thats a different story)

    Back to the OP, your 750W seasonic can handle 3 5850s just fine, is it the X-750? Great PSU you got there..

    In you still want to go with the dedicated PhysX card, grab a cheap GT240, it should handle the job just fine without having much of an impact on power and heat.
