Upgrade options from CrossFire

I have two PowerColor 5770s in crossfire right now, and I'm debating upgrading my computer from Phenom II to a Sandy Bridge setup.
My main question is, should I go for a 6870 or a 6950? I've been trying to find a review that compares the performance of 2 5770s to other setups, but I'm having a hard time. From what's I can find, they perform similarly to a single 5850, so a little worse than a 6870 on average. I'm mostly looking to switch platforms and "reset" my upgrade path rather than get a huge graphics performance boost, but I don't want to hinder myself by cheaping out on the single GPU. I also recall that the 69xx series scaled significantly better than the 68xx series when it comes to crossfire.

Thoughts?

    There's your VGA charts you can use. The 5770 CFX listed is for 2 5770's, I double checked it, so use it for comparison.

    In short, a 6950 is going to be a better option for you to upgrade, not only in terms of a single 6950 outperforming your current setup, but for future upgrades it will definitely scale better on CF.
  2. i agree with boris, but you might want to just do the videocard for now. in a month bulldozer will be out and might look like a better option for a new system and if not sandy bridge will likely be cheaper to compete.
  3. Nice site! Thanks a lot, that's helpful.

    True, it's definitely a good idea to check out bulldozer. I need to raise capital for an upgrade anyway, so I'll definitely wait a little.
