No buddy , even with physx off, ati is lagging behind nvidia high end cards this time. The 6970 & 6950 trails behind the gtx 580 and gtx 570 duo in all the benchmarks and all resolutions.
And talk about sli vs cf, sli needs some further optimisations for the newer cards and probably a new driver would fix it. And the competitor of 6850cf will come in the form of gtx 560 sli. This time its all nvidia in the top segment and expect that trend to follow till the midrange territory.
If ati can get the pricing right, we can see some decent competition.

Nice piece of info buddy. But what has bus width to do with die size?
If manufactures know about "quantum tunneling effect", why will they fabricate thinner dies in the first place? A sillicon die which has more area can incorporate large no. of transistors & nano architecture i.e 55nm , 40nm refers to transistor size.
Transistors being small in size, can be incorporated in smaller dies but without sacrificing their number strength because total no. of transistors is directly proportional to performance. But to reduce power consumption and heat, the die shrink and nano fabrication are necessary which also cuts down cost.
Both amd and nvidia are currently using 40nm transistors in their dies but amd's die size is smaller than nvidia and the latter has more no. of transistors.
like Ico said 60% hit with enabling that bu**sh*t with a single nv card, an enthusiast surely will buy an xtra card for phys(if he really a fan of that).so, it is indeed not a even tiny factor for choosing gfx card...but , seriously ,in case of mine(and i think other price concern players) physx s*cks balls...and again it is already being saidthat those effects with physx ,could easily be achieved by in_built softwares.physx is worthless, coz, it isn't optimised for todays cpus, no SSE2 instruction,no multicore optimised.nv said ,'it is developer who made the choice ,we have those sse2 supports'. my question is 'why developers made the choice?
Post properly cause that sms style looks crappy imo.
Amd has no trick up its sleeve from a software point of view. nvidia did this to gain an upper hand & if more games supporting physx sell more nvidia cards will.
Why would nvidia want amd cards to support physx? Thats the reason of not adding that sse2 instruction just because to cripple amd in nvidia titles.
And a person who wants physx would never go for an amd card even high end ones. They would prefer nvidia and current amd owners who wants to go the physx way will add a second nvidia card.
Nvidia is supporting more titles than amd & some are even aaa titles.Thats why the developer does what nvidia tells them to do.
And if that sort of effects can be done without physx code, why doesn't amd do it and then do the talking. Atleast we will have some fair competition.
yea, in comparison to 6970, 570 is a better buy...but wait for 2~3 driver updates from amd.But, in price, 6950 is unbeatable.
in tesselletion, see this.

AMD Radeon HD 6970 and HD 6950 Review - Page 15
nd this
After amd's 2-3 driver updates, nvidia will also have 2-3 driver updates.
The bottomline is both the caymans lag their nvidia counterparts in all the benchmarks. Even the 570 touches 6970 in performance. Nvidia will release a driver to improve its sli performance.
In tesselation amd still lags nvidia and in higher resolutions the gap increases.
If anything will save amd caymans now is going to be pricing.
AMD is already fair, it's nVidia which started that PhysX thing; one company which was being dominated by AMD since 3 years needed a gimmick to sell their cards off during that period because they knew they are getting spanked all corners.
