Yes , it was me and I stand by that theory. It was 20% faster then gtx 480 and cost less. Scaling was very good and has gotten better. I also was talking about 1900x1080 ,not 2500x1600.
The 6850 crossfire numbers are no where near 20% faster then a gtx580. In this case its just not worth it. Then you have to factor in a new psu with your upgrade to sli'd gtx580's also, or the fact that adding another 6850 will probrobly suck in tri fire.
We are talking about 1080p.

6850 CF is faster than 460 SLI
And if you look at Anand, Hot Hardware, and Sweclocker results, the 6850s have better scaling than the 460s. So the 6850s are just as good, heck possibly even better, of a value than the 460s.
You were recommending 460 SLI when they cost $220-$230 each, but you don't even think about 6850 CF when they're $180 each? At least try to hide your bias (which you can only really do by being impartial ) You're one of the few clamoring about price/performance, and 6850s (or $190 460s) are just as good of a value compared to the GTX580 as the $200+ 460s were compared to the GTX 480. Facts: 6850 cost less than a 580 and are just as fast, if not faster, much like how the 460s cost less than a 480 and were faster. But there is a tradeoff: The 6850s performance advantage is smaller but the cost difference is higher. In the end we're in the same situation, except you have switched philosophies.
And why are you clamoring on about a new PSU and Trifire? You make statements but they really don't make any sense. You need to flesh out your thoughts. In any case, I'd consider going with a single 580 or two midrange cards giving you the same upgrade path. For one I doubt it will be really that beneficial to SLI the 580 anyway. It's price is most likely going to stay relatively high (like the GTX 280, 285, and 480 before it), especially compared to whatever new products come out, and you will require a pretty beefy power supply. So if you go with a single 580 then you're going to be under the same philosophy that you should just get the next fastest single GPU, and this is exactly the same kind of upgrade you would be doing if you had gone with two 6850s or 460s.
And honestly I dont trust CF drivers yet ,but there looking better.
Crossfire drivers were total crap at the time. Remember the gtx460's beating the 6870's?
Sli drivers as a whole are much more consistant than CF.
That is changing though, thank god.
The 6800 series has excellent Crossfire drivers and performance right out of the gate. Whatever argument you are making (as you probably meant the 5870 instead of 6870) is not applicable, until AMD does indeed screw up the 6800 series.
I hear what your saying and I dont doubt the 6850's are a good value, but does it outweigh the negatives of CF/sli for 25% more money? Remember you also have no real upgrade path with sli/CF, thats where the 3rd card scaling has you lose money. On the other hand going from a gtx580 to sli'd gtx580's, you get your moneys worth
Hmm I quoted this to debunk it but I already addressed everything here anyway. Read up^.
It's funny seeing the tune being changed.
