Graphics upgrade: one more 5850 or 6870

My rig is currently equipped with only one HD 5850.
Should i buy another 5850 and run a crossfire system (i do have the psu and mb required for this), or just upgrade to a 6870 and remove the 5850?
I'm inclined to go with the first option, because the performance difference from 6870 to 5850 is quite small, but what are your toughts?

  1. the performance difference between 5850 and 6870 is almost negligible, so that wouldn't really make any sense.
    Crossfiring would give a bigger increase but it has its problems as well, though some people seem to get it running perfectly fine while others just dont...
  2. Yeah thats what i tought too. The performance upgrade isn't considerable. I think I'd get crossfire to work good, i have a Corsair 750TX psu, which is quite enough, and a Gigabyte 790fxt-ud5p mobo, so both cards would run in 16x mode, which is quite nice considering most mobos other than i7 ones don't have this..
    The problem is I may not be able to buy a hd5850, they're kinda out of stock, I'm having a hard time finding one, but i should be able to get one eventually.
    Thanks for the answer!
  3. No point going to a 6870. If you're upgrading from a 5850 to a single card, I wouldn't do it for less than a 570 or 6970.

    CF 5850s kicks ass. Do it, especially since you can get a 5850 for $150.
