Sell it before the prices drop. Avoid crossfire issues. Use less power. Have the latest and greatest!!! thumbsupsmiley.png

Just get a 2nd 6970, selling it and buying the 7970 is not cost effective at all in your situation. The most I can see you getting for your used card is in the $200 range then you have to drop another $350 or so to get the 7970. If you kept your current 6970 and spent that $350ish on a 2nd 6970 you would greatly outperform a single 7970 in the upwards of 30-40% faster. My 2 6870's in Crossfire are about 15% faster than a 7970 so it's kind of a no brainer.

That's true also. It depends on which games you play too. Especially with driver issues for Crossfire. Although most games are sorted out by now, some still have issues. eg Borderlands is slower with 2 cards than one (for me with 2 x 6870) Microstutter is another unfortunate fact of life for Crossfire owners.

 

Some modern games that make heavy use of tessellation will also benefit from the newer cards technology. There's no logic really in upgrading video cards lol. You don't need to, but do you want to?

It all comes down to numbers honestly, if he plans on getting a second 7970 then I say go for it but if this is just a jump to a single solution it's a loss in performance per dollar vs. a second of what he already has. There are about 3 games that do not run Crossfire properly now and those games are not exactly relevant anymore so I think it really comes down to price/performance ratio. Is the 7970 a step in the right direction for AMD? Sure it is, is it really worth jumping to over the last gen flagship? Not really, an 8970 would be but not this.

In terms of micro stutter I don't have a problem with it or don't even notice it, most people are just hypercritical about stuff like that rather than realistic.

I switched from 2x6970s to single 7970 and happy with it. performance wise it'll be a little slower compared to CF 6970s but tessellation power is better than those 2cards. I would suggest to buy 7970 ONLY if you have enough budget and if you plan to grab another 7970 for CFx in near future. If not, 2x 6970s is a powerful setup already with 2GB ram, I think it can still hold its ground for another 2years smile.gif.

I've been running Crossfired/unlocked 6950's for almost a year now and have had very few Crossfire-related performance issues. My system tears through every game I've thrown at it, with the exception of Skyrim until I updated to Catalyst 12.1. Then those issues went away as well. The 7970 is just too expensive if you're looking for good price/performance. It's also overkill for 1080p or lower resolution. Only worth it for 2560x1600 or Eyefinity in my opinion.

In terms of Skyrim I would not even mention that game, one of the most god awful console ports I have ever seen.
