3d mark 06 the 4850 in crossfire scores 20923
and the gtx280 in sli scores 21269
this is at 1280x1024
going with these results is it safe to say that the R700 will beat 2x280 in sli
R700? A single one beating a pair of GTX 280 cards? No, that just seems rediculously doubtful. It's pretty clear that once you remove the memory bandwidth problems that appear to be strangling the 4850, nVidia's in for a world of hurt. I mean, seriously... 2.5 times the shader and texture power, plus 72% more memory bandwidth over the 3870... Given that the 4850 does more than the 3870 with less bandwidth, you're going to see a performance increase of massive proportions.
However, for the 4870X2 to best a pair of GTX 280s in SLi, that would have to mean, at the least, that a single 4870 would be pretty close to comparable to a GTX 280. Which, I suppose, might be plausible, but even I don't see it beating the GTX 280; the crippled 260, almost certainly, but not the 280. Then after that, you'd need for SLi to be significantly worse in efficiency compared to the X2 card setup.
To be honest... while right now's a bad time for nVidia, they're not going to get owned out of any excuse for existence. Rather, it's just going to be what I predict will be a rather brutal pincer attack; the 4850 will first bring up the rear, eliminating nVidia's ability to sell G92-based cards while retaining both competitively and profitably, and then the main assault will will come with the GDDR5-based 4870, which will likely land between the GTX 260 and 280 in performance, and then the 4870X2, which will best the GTX 280 by a solid margin. (perhaps 50-60%?)
Individually, any one of those cards wouldn't really hurt nVidia; the green giant is quite used to raking in its main profits from pretty much any video card that costs $150-200US and up; the cheaper cards that are so much more popular with OEMs have historically been a strong domain for ATi/AMD. However, with these three cards all together, it will call up a serious question as to whether GT200 will ever be able to be a financial success for nVidia, and likewise, putting an early nail in the coffin of the G92 for good measure.

but there's only 1000 points between the 280sli and the 4850 crossfire, if ati get the scaling right who knows

This is not wholy true
It really just depends on whether or not Nvidia can get their SLI driver on the same level as ATIs new Crossfire that is speculated to be released with the 4870x2
If the 4850 is any indicator, it shows that the gpus scale well in Crossfire mode
Actually, AMD themselves have stated that their aim was to create scalable gpus for Crossfire.
What I think is going to happen in reality is this, and i'm going out on a limb to say this but its just sort of a gut feeling i'm getting.
4870 is not going to be a huge jump up single card vs single card over the 4850. There will be differences, but it won't be astronomical like people are expecting.
However, what the 4870 WILL be able to do if the 4850 is any indicator, is get /significantly/ better scaling in Crossfire than Nvidia can get in SLI. This may be where ATI will really rock Nvidia is in the multi-gpu scaling department. The 4850s scale incredibly well from what tests i've seen.
Meaning as thus, 2 4870s might not beat gtx280 SLI, but for the same price as gtx280 SLI - you could get 4 x4870 Quad crossfire on an AMD790FX platform - or wait for the 4870x2 for Quad crossfire/Tri crossfire on the Intel platform and achieve better performance per dollar at varying points of reference.
The 4870x2 is supposed to be superior to a Crossfire bridged gpu setup - its supposed to have a better controller, I don't totally understand this business yet cause there isn't enough information - but it is "supposed" to have a much better Xfire technology than the 3870x2 - This should put the 4870x2 Quad crossfire above Nvidia's 3way SLI gtx280 if it scales the way that they have implied it will.
Just pure speculation, but going by AMD's marketting this is what i've been gleaning.
Yeah, so basically, unless you want constant screen tearing you're going to need to use VSync. Which will limit FPS to whatever the Monitors refresh is, so anywhere from 60-120? fps. Least I think the new LCD's that are coming out are 120hz refresh.
What I really care about, is whether the cards have enough horsepower to keep FPS constantly above Vsync rate, especially with AA, and AF, and HDR enabled, at the resolution I play at, being 1680x1050 on my LCD. Which most modern cards are capable of, with filters off. I'm just glad ATI appears to have fixed the problems with poor AA performance. I'm also mainly curious to see whether a 4850 or 4870 will Xfire with an older 3870, that way I could still use the Toxic edition 3870 I have. I also hope Sapphire comes out with a Toxic/Atomic edition card for the 4800 series. Damn nice GPU coolers on em.
Which leads me to say something. I kinda wish these reviewers would use resolutions that most people will likely game at. 1280x1024 for those that have regular 19 and 20 inch 4:3 Displays, 1680x1050 for those that have 20-24 inch 16:10 displays, and then res's like 1920x1080 for those that have full HD capable displays, anything higher would just be gravy for those with large budgets.

That, and crank up the eye candy, go 8AA, at least, and of course 16 AF, these are good cards that can do this, why not show it ?

I completely agree. Who cares about the performance at 200 fps and running 1280x1024.. I just want to know which card can hold its own at 1680x1050. With AA/AF. And the min/averages.
If it can still do 8AA and give good fps, why not?
