I'll finish up with this: if the 4870 X2 turns out to be faster than the GTX280 it will be a hollow victory as far as I'm concerned.
If you look at how seemlessly multiple CPUs can chug through an SMP-enabled application such as video encoding, you've gotta keep the faith that someday dual GPUs will be capable of 100% gains over a single one.
If the X2 can beat the GTX280 without any major driver issues, AMD will have pulled a major rabbit out of their hats IMO. I personally see the lack of texturing units as the 'achille's heel' of the 4870, but time will tell.

Your first point assumes the current bridges are a limiting factor for communication between GPUs for CF and SLi- which I've never seen referenced anywhere. Link to this needing a change?
Radeon HD 4870X2 faster than GTX 280, no microstuttering?
Written by Andreas G 07 June 2008 19:39
Radeon HD 4870X2 is the high-end part of the Radeon HD 4000 series. Like the Radeon HD 3870X2 it sports two linked GPUs on a single PCB. The exact nature of the link is unknown, but we've been told that AMD has done some major changes to the linking since the last generation, since AMD was quite displeased with the performance of the 3870X2 bridge chip. According to a recent post at VR-Zone, citing a source who does not want to be named by name, Radeon HD 4870 will not suffer from microstuttering since the communication will be done through the memory instead of a bridge chip. This should also have a positive effect on the CrossFireX performance.
Microstuttering is a result from using AFR (Alternate Frame Rendering). The frames are then sent to the monitor at an uneven rate (more like two and two instead of a steady flow) which causes stuttering. Running two Radeon HD 4870X2 in CrossFireX for three or four GPUs should still have the same rendering problems though, I.e. if AMD hasn't come with another new feature for the Radeon HD 4000 series, but we're skeptical there.
There will also be Radeon HD 4850X2 cards which will instead use GDDR3 memory and lower clocks overall, but this is an optional card for partners. The performance of this card will of course vary depending on the clocks, but it should still be in the high-end part and able to compete with the GeForce GTX series, while the 4870X2 and its GDDR5 memory is estimated to beat the GTX cards with a margin. Both cards are slated for a fall launch.

According to OBR (who definitely has a GTX 280) HD 4850's in CF are faster than a single GTX 280.... in whatever benchmark he tested (probably Crysis). And he's no AMD fanboy either.
If HD 4850 CF is faster.... HD 4870 CF should definitely be faster as well.

hahah.....the 4870x2 may be faster than gt280...but the 4850 won't be....just wait and see.

4850's in Crossfire.... not a single 4850.
I doubt ORB is lying and it is not that hard to believe either. 4850 CF should be faster than a 9800GX2 and in certain situations the GTX 280 might not be much faster than the GX2.... I think 280 will excel in high res + AA/AF where the GX2's 512MB framebuffer wasn't enough. But in normal situations.... I don't think the 280 will be that much faster.

No offense intended, but an unsubstantiated rumor from a "source who does not wish to be named" is not information anyone can take seriously.
I hope you're right though, the people who desire dual gpu card that are sensitive to "microstutter" would benefit by this.
I don't think it changes a lot for most people though. SLi/CF have been around for years, reviewed literally hundreds of times.
The "microstutter" hasn't been a big deal in any of those reviews, nor pointed out by users on forums till this year.
The GTX280 will still have advantages over dual gpu solutions (including 9800GX2) whether they microstutter or not.
Fair enough, it's a rumor but more of them are coming out and NV fan boys are getting more and more worried that AMD/ATI is heading in the right direction and NV is going to be behind.

Not sure if that has been posted yet. Picture of Gainwards box. On the bottom in fine print says it requires a 550+ watt PSU to power the GTX 280.

actually i think AMD is heading in the wrong direction... But they are doing it on purpose to reach fusion, which will be the ultimate mid-range.
But for high end they are totally missing the mark.

Ok now I really believe the GTX 280 is close. This is normal for a nvidia launch - dampen expectations. You can bet on release day with new discovered drivers, the GTX will not disapoint.

more like dual GTX 280's...
edit: plus, the reports that 4850 CF beats a single GTX 280 are still far from verified. ATI would have to make some pretty big strides in a short amount of time, considering that their last dual card just edged out the 8800GTX which was over a year old at the time of the 3870X2's release.

I wouldn't bet the rent on that.

I wouldn't bet the rent on that.
Thermal constraints mean a GT200-GX2 on 65nm is impossible. Not only that, but imagine the PCB needed to accomodate 2x 576mm^2 chips with huge IHS. Not only that, but nVidia would have to use GDDR5 memory as it would be impossible to have 2x 512-bit bus for the 2 GPUs. And the thing would have to cost about $800-900 for it to be profitable.
55nm GT200 would still be above 400mm^2, so I highly doubt we would see a GX2 card from that. If we did, the clocks would have to be so low it wouldn't be worth it.
