im demanding if i should buy 2 4850s cuz its cheaper than buy 4870 and CF it or should i wait for 4870x2 it will be equal as 2 4850 cf? but 4870x2 will be more expensive that 2 4850s?

Wait for the x2 definitly worth wild http://www.tomshardware.com/news/A [...] ,5816.html has 2gb of GDDR5 effective cost estimates 500-550? I have high hopes for this card, break some new records

Here's hoping that 2GB will be shared as opposed to 2 seperate 1GB buffers.

i have read a few articles on the 4870X2...while details are shy i have heard mention that unlike the 3870X2's, there is no pci bridge and the gpu's are truely hardwired into CF sharing the same frame buffer. In fact the drivers even see it as one gpu rather than two. but kraynor is right...here's to hoping. FUD and facts are seprate. be nice if its true though. think of running six gpu's that scale like three...cold shower time.

oh man, just thought.....time to take another cold shower!

The 4870 is about 20% faster performance then the 4850. And the 4870 is $100 more. I'm no Rocket Brain Surgeon, but that number does not add up.

I would rather get two of these bad boys

in CF then a X2. Until they make liquid nitrogen available to the public, I'm staying away from the X2 (i.e Lava Flow Cards).

I read that the 4870X2 outperforms 2 4870s in CF by 15%... not sure how credible the source is though

Keep in mind the GDDR5 memory is rather expensive : /. It will get cheaper later in the year though.

Once GDDR5 becomes affordable ATi will probably announce GDDR6

That is true and the possibility a smaller die keep ATI one step ahead of nvidia

AMD can't even get their CPUs to 45nm, let alone their graphics chips... but here's to hoping!

Oh, and to the OP: what specs do you have? what CPU, and what resolution will you be using? And also, do you have a board with dual x16 slots, or just two x8s?

Well I don't think we have seen much good out of thier amd CPU's but their graphics division I think could manage, It would be a big leap though. very chalenging but if they pull it off wootz like they did with the 4xxx series.

Not truly on the same topic but very near here is something interesting:

So 950MHz GPU and 4.8GHz Memory? Can anyone say HOLY S*************T?
