ATi 4870X2(R700) PCB Debut

[AriciU]

I'm thinking about a tri-CF setup (1x4870X2 + 1x4870), because I already got a 4870.
I really doubt that there won't be any microstutters, especially in high resolutions when 512MB won't be enough.

What do you think about that?

Running the 3rd 4870 on an X4 slot is going to get you nowhere. Check out 3 x CF scaling and see for yourself. It scales like crap to put it in words.

But you only need 2 pcie slots. X38/X48 offer 16lanes/16lanes (2.0) and P45 x8/x8 (2.0)

Yeah, i just re-read that and noticed. The "tri" part confused me... i was thinking of 3 physical cards installed. Hopefully it will scale properly. We'll just have to wait and see

But you would have 2Gb on the X2 and 512Mb on the 4870 and only use 512Mb I think.

Offtopic: anyone know if you have to do anything special in Vista 64 to get crossfire working properly? I just ran Vantage and got only ~9k / ~26fps for GPU tests and i noticed people usually get around 13-14k at 4000-4200mhz with ~45fps for the GPU tests. Using hotfix drivers... thanks.

I was wondering the same thing. I hope it works fine on Vista 64.
