Huh??? I said the exact same thing a few posts ago?
Now you are agreeing with that yet before you wasn't, make your mind up!
I never said the 4870x2 wasn't the fastest card why would I disagree with that statement? The 4870 however is not the fastest GPU - the GTX280 is

. I know you are still getting to grips with the quote and edit buttons so I will forgive the misqoute.
What is s775? Do you mean skt775? DDR3 and 's'(?)775 are fine if you have the right chipset. skt775 is not a chipset, its socket. There ya go, you are learning all the time.
Uhh, seems like you're grasping at straws really. Why should it matter how each camp achieves their speed? So what if NV have the fastest GPU, that's not really any different to ATi using 2 RV770s in one to gain the top end.
Why do you think NV haven't tried a GX2 yet? It's most probably totally unrealistic at the moment. Too big and power hungry to easily get into one card. But the old argument of
you can't compare 2 GPUs to 1 GPU, if it's faster and cheaper, then it doesn't matter, you can tell yourself all day what ever you want to hear, it's not gonna change reality.
If a RAM manufacturer (all in theory) realised that if they increased the number of RAM chips on their RAM modules, the performance would go up quite a bit, you'd get laughed at for saying,
ah, well no, it doesn't count, because that module has 16 RAM chips, whereas that one only has 8.
Doesn't make sense at all, you have to be stupid to use that argument and say it's like comparing apples to oranges. I can get much faster performance by buying 2 4850s and crossfireing them over a GTX 280, for much less money too, why would I even consider it to be 'unfair'? Because they're using a method that works to get more performance for less money?
Common sense tells you that 99% of people will go for the cheaper and faster solution.
Look at it this way. I need some really strong glue to fix something together. I've got an epoxy glue, and I've got a one part air drying glue. The epoxy glue is cheaper and stronger, but comes in 2 tubes you've gotta mix together before anything happens, whereas the air drying glue is just apply and wait until it dries.
With the epoxy glue, I've gotta squeeze equal amounts from each tube and mix them together, then apply and wait. Some might think it's inconvienient to go through this step, but it's high strength I need, so epoxy is best.
Would you say,
ah, but that's an unfair comparison, epoxy glue takes two tubes that need to be mixed together, whereas the other glue you just squeeze out and use?
At the end of it, you're left with same result, whatever you're sticking, is stuck, but the epoxy is stronger and cheaper. Just because it takes 2 tubes against 1 doesn't really change that it's cheaper and stronger. Now apply this to your idea that compariing 2 GPUs to one is unfair.
I don't really expect you to change what you think about multi GPUs, but you can't go around telling people that their views are invalid, just because you don't agree with them, because there's greater chance of their being more people that think your view on the matter is the invalid view, than there are people who would agree with you.
At the end of the day, there's not much to complain about with multi GPU set ups anymore, as it's been demonstrated that 100% scaling is achieveable. COD4, FEAR etc.
