Get another 5770 or 6870?

Hey everyone. Looks like its time for that upgrade! I'm on a limited budget so the most I can push is in the 6870 price range. BF3 has been put on hold cuz I need to upgrade. I found it pretty difficult to find 5770 crossfire benchmarks on the newer games, but I think it's pretty close if not better than 6870. What do u guys think?
 
You would see about a 60% performance increase from CFX. However, not all games work well with CFX either. Going with a 6870 would be about the same as 2 5770s in CFX. I am not sure that either of those is going to be sufficent for BFE depending on your resolution and what settings you expect. For instance with 1920x1080, if you are just going with medium settings you should be fine. High settings may be a little bit of a problem, ultra settings will be right out.

A 6870 has almost identical performance as the 5850, so this chart should give you an idea of what to expect by moving up from your 5770.

Also, the 5770 scales well in crossfire and will give you up to 90% improvement in supported games.

Looking at the chart, I would probably pick up a 6870 for around $150 and sell off your 5770.
