Yeah, it'll prolly do as much as WHQL did for ensuring bug-free drivers...

16x CSAA quality truly lies slightly above 4x MSAA and underneath 8x MSAA (always considering Transparency AA too). Apart from the slight performance drop, many won't even notice in real time LOL
So, in reality, the feature is offering x6 AA quality over-all -- when it works in a title.
Allow me to express some thoughts on the rumoured RV630 specs.
It says Kohinoor GDDR4 consumes 127 W, I think this TDP is made up. The retail R600 board consumes 240 W when R600 is built on 80 nm RV630 is supposed to be 65 nm. An R600 built on 65 nm is supposed to consume 180 W, cut the chip by half to make a mainstream card and u will get 90 W. Am i right?
If there's an R680 anywhere even close to done, it's being hidden very well. Hints at R580 were thicker on the ground (much, in fact) at the time of the R520 launch. I pretty strongly suspect anyone who's looking for an R680 to ride in at the last moment is going to be 1) deeply disappointed and 2) have done it to themselves because there's no rational reason to think so that I've seen.
I would imagine that the only way this could even have some weight of truth is if ATI was able to shrink the die to 65nm. Something i highly doubt they could accomplish right now with the R600 core.Maybe the R600 already the R680
These are my theories on the delay.
1) AMD decided to hold the R600 back for a joint launch along with their other respective family(RV610/RV630). A complete and total launch mind you if you call it that. AMD will be able to meet all price points of the market.
1) Given to how close R680 is to completion(guessing), AMD decided to hold the R600 back for a joint launch along with their other respective family(RV610/RV630). A complete and total launch mind you if you call it that. AMD will be able to meet all price points of the market. R680 for $600, R600 for $500, RV630 for $200+, RV610 for $100+, and downgraded R600 variants meeting the $300, and $400 marks.
Maybe the R600 already the R680
Errr.. No. It offers 16x edge sampling. And 4x Transparency sampling. And will offer in some cases "Reduced" sampling on very thin objects. 6xAA isnt even a remotely close comparison to 16xAA. Even if your trying too find some common ground to make a base comparison. There are times 16xAA can look better than 8xQ. And times it can look worse. Dependent exactly on whats being rendered.
It is with very thin objects and stencils. I highly doubt x16 CSAA performance offers comparable image quality as X8Q over-all. Do believe it may in some cases.
3) AMD is almost done with their 4x 16x PCIe slot chipsets, and for marketing reasons, decide to launch both at the same time to show the power of 4 R600's on editors day.
Maybe they aren't just looking at a family launch but an entire platform launch. CPU, GPU, chipset all at once. Just a matter of how close the chipset is and whether or not Barcelona is close. I can't imagine a quadfire setup not being CPU limited. Nearly 600GB/s of bandwidth should be enough for a little AA/AF at higher resolutions. I'm not sure you can even push the resolution high enough to make that thing break a sweat.
It's a little hard to stomp all over the competition if you're CPU limited so I'm sure they're pushing to get something out the door that can compete performance wise. Even if the CPU is bordering on a paper launch.

And I already explained that Opterons work in Quad-FX mobos.Barcelona's a server chip.
