Default crossfire 6870 reviews?

I am upgrading my 4870s to 6870s, i was contemplating whether or not i should do it.

well, after checking this out, i think im sold.

it's seems weird to me, that a single 6870 is outperformed by a single 5870, but crossfire 6870s seems to obliterate a 5970 (i would assume it would destroy crossfire 5870s as well).

is that weird to anyone else?

Have you guys been able to test this for yourself, because im still flabbergasted that this is possible for cheaper and with less power.

What was weird to me is that AMD had such poor crossfire performance. It's good to see they seem to have figured it out.

Anandtech's review shows crossfire throughout and the 6850 Crossfire is typically faster than GTX 460 1GB SLI Whatever AMD did to Barts, it worked!

Nothing was changed in the CF scaling between Cypress and Barts.

Hmm... that appears to be true... any differences in scaling are small enough to not be meaningful. It does seem that the 6850 CF gets closer to the 5850 CF than the 6850 gets to the 5850, but it's a pretty small difference. Maybe I've been reading [H] too much, where CF always gets panned in favor of SLI.

Yes however i love how it doesn't show other equivalents in crossfire or sli, which as always skews results comparing 2 cards against 1. How about seeing 470 sli against 6870 xfire vs 5870 xfire eh?

actually, i changed my order, and yea, 6850s are way cheaper, and for my resolution, i am thinking 6870s are too much.

i got the xfx 6850s, after tax and shipping(wow, HST IS A BITCH NOW, like 60 dollars on tax for the 2 cards) for 524, it would have cost me 644 for the 6870s.

so, 125 in savings.

Seems like the best choice of upgrades for me, i think the 69xx series would have costed too much for me to afford.

ASUS Radeon HD 6870 CrossFire Review - Page 4/25 | techPowerUp

works out to be 20% savings to go the 6850 route, for 13% less performance (i know it will vary by system).

is it simply that the cards are just that much better?

even then, AMD is proving to be king of GPUs imo.

I'm loving thte 6850 even more after checking the overclocking review here.
Being able to overclock it that much is making me drool.
