In an attempt to have a properly named thread, and to keep from getting it locked, lets try and keep it calm.
The article claims no more resolutions limitations, like the X800 Crossfire had. It also claims that you no longer have to lower the HTT in the new chipset, which is a nice bonus for those who overclock. They also say the XT/PE is likely to be here mid-Januarary. And that X1800XT Crossfire is faster across the board than 7800 GTX 256mb SLI.
Matthias99 broke it down pretty well, so I quoted him from another thread.
Lets try to stay on topic.

No exact performance numbers, at ATI's request (since it's still a beta product).
A few interesting quotes (all emphasis added):
We took the opportunity while talking with ATI to ask about the crippling delays of the ATI X1800XT and the X1xxx family. There are so many rumors in the market place; we wanted to hear ATI's explanation of why it took so long for X1800XT to make it to market. Was the problem the 90nm die-shrink as many had speculated?
ATI told us emphatically the delays with X1800XT were NOT the result of the die-shrink to 90nm. We were told the issue was a defect in a third-party IP (Intellectual Property) that was used in the x1800XT GPU die. It took ATI quite a while to find and correct this design flaw. Why does this matter? Since this flaw was specifically related to the X1xxx family, design work continued on future video cards, and there were no delays on that front. Development continued on introductions that will follow R520, which means the R580 GPU is still scheduled for launch in January.
So how well does RD580 overclock? We can't quote exact numbers, but we can tell you the RD580 BIOS has not yet been tweaked for memory compatibility or top memory performance. We also used our own known OCZ PC3200 Platinum Rev. 2 dimms in testing since we are very familiar with how they perform. Even with the untweaked BIOS, we still reached overclocks even higher than the excellent performance of the Crossfire AMD Reference board! We can only speculate where this board might end up, but it is already a very exciting overclocker.
We confirmed that the new compositor chips used in X1800XT Crossfire do indeed run fine in Crossfire mode at 2048x1536. ATI tells us there is no limitation in the X1800XT compositor that would prevent even higher resolutions from working as they should.
While the exact performance results achieved comparing X1800XT Crossfire with 7800GTX SLI can not yet be published, we can tell you we benchmarked with F.E.A.R., Quake 4, Splinter Cell - Chaos Theory, Doom 3, Far Cry, and 3DMark05 at 1600x1200 resolution with 4X AA and 8X AF enabled. ATI X1800XT Crossfire won every benchmark over nVidia 7800GTX SLI in these tests.
We also ran standard scores (1024x768) for Aquamark 3, 3Dmark03, and 3Dmark05. Once again Crossfire X1800XT outperformed nVidia 7800GTX SLI in every benchmark.
here is no doubt that the nVidia 7800GTX 512MB, which everyone expected would launch 2 days ago as a 7800GTX Ultra, would likely win a head-to-head performance test as single or SLI when compared with the single X1800XT or Crossfire. However, ATI clearly believes the competitor for X1800XT is the $499 7800GTX and not the $700 7800GTX 512MB. ATI was quite clear they will be introducing a "PE version" of X1800XT to compete with 7800GTX 512.
And the conclusion:
Based on what we have seen in this RD580 preview, the worries at ATI right now are more about the present than the future. Future solutions look very competitive and exciting to the market. ATI seems to be caught in a release "Twilight Zone", but as they work their way through current release nightmares, the future looks as if it could be very bright again for ATI. Certainly the upcoming RD580 Dual x16 chipset, X1800XT Crossfire, and X1800XT PE look more than competitive. Add to that R580 is just around the corner and it looks as if ATI has the goods coming to erase the last nine months of disappointment.
Sounds like a winner if they can get the damn boards into people's hands.
