Doesn't seem too good to be true. 100% performance increase from a next gen part has happened numerous times in the past. This also is the first time ATI is using the code name Rxxx in a long time. They used to use Rxxx for their top end and RVxxx for their value lines. R800 for 5870 X2 and RV870 for 5870. The use of the codename R instead of RV for their top spot seems to say that they are aiming for a top dog position.
don't know about using "R" instead of "Rv", but huge performance increase over previous gen is almost commonplace. In fact, most recently 4850 is quite a bit faster than 3870x2, 4870 is a LOT faster than 3870x2, 4870x2 is probably 100% or more faster.
Just a little correction. 3870x2 is much faster then a 8800gtx which is = 4850. 4870 is more or less = to a 3870 x2. 3870 x2 is slightly slower then 8800gt's in sli which = a gtx280
8800gtx is not = 4850. 4850 is actually better than 9800gtx, which is what started the whole 9800gtx++++--**@ bs that we saw last year. I really hate to throw up anything from toms on you, but:

4850 actually is faster than 3870x2 in many scenarios, and the 1gb probably beats 3870x2 every time. However, I was mistaken when I said that it was "much faster". The "much faster" card is the 4870.
8800gtx vs 3870 x2 @ Anandtech

Where crossfire works the 3870x2 beats the 4850,9800gtx,8800gtx.
Anandtech benches here.

With the new drivers today and much improved crossfire performance I believe 3870 x2 would pull away even more. The 4870 looks to be slightly faster.
those anandtech reviews were done with little to no AA. The first review doesn't even list the 4850, the 2nd one shows them within a couple % of each other, and the third one shows about a 12% edge for 3870x2. However, what happens when you crank up the AA?
http://www.techspot.com/review...radeon-4850/page6.html
not a huge 4850, but certainly this shows an increasing advantage as more AA/AF are added. I personally can't tell the difference between 93 and 85 fps, but that is still about a 9% advantage for 4850. crossfire is clearly scaling in ET QW, too, so don't say that deficiencies in xfire are to blame for this. 4xxx has implemented AA/AF MUCH better than 3xxx did, so my gut tells me that there will be more where this came from:
http://www.techspot.com/review...radeon-4850/page9.html
this same article lists several games where 3870x2 has an advantage, even with AA, so it's not clear that 4850 was superior last summer. However, it's also not clear that 3870x2 is superior, either.
here's some more info from techreport:
http://techreport.com/articles.x/14967/4
this next one is interesting, it shows 3870x2 with an advantage (at unplayable frames of course) in crysis, but in assasin's creed you have 3870x2 with a 40 - 34 advantage in average but 21 - 25 DISadvantage in median low framerate.

slight advantage for 3870x2 in theoretical perforamance here with 3dmark vantage.
http://techreport.com/articles.x/14967/8
no scaling in race driver grid. this has probably been fixed by now so not a fair comparison.
All of these tests were with a 512mb 4850. Lower power draw, single slot, better AA/AF, NOT xfire. Performance is in the same ballpark as 3870x2. 4850 has certainly benefitted from the past 14 months of cat drivers as well, probably more so than last years sandwich 3870x2. However, even assuming that they have both improved equally, I would still much prefer the non-xfire solution. Which would YOU pick? Also, if you got really edgy you could spend a few more $$ and get the 1gb 4850 for higher res, though it tends to get unplayable in many titles byt he time the extra 512 mb comes into play.
