Thanks for sharing

Ooooh, graphics card heaven avenue
Nice scores with this graphics cards mix

I can't imagine the ambient temp with this system inside a mid-high tower case

Watercooled VGAs + CPU on LN2 would be nice [ just an idea ]

Nice benching! Considered moving to a colder country?

[keldererik]

Four on a row looks great

[EXPANDER]

Nice benching

[2fink]

really nice results! i think 4 3870 should be really fast to run.

I am very curious to how 4 HD3870s would compare to 2 HD3870X2s.

A lot of guys tried to make 4 3870s work properly, but nobody so far managed to ... scores are a bit low, due to the absence of a proper bridge ... Shamino made a custom one, for better performance, but no luck ...
We 'll see

Ah, I see.
I think they will get it working, one way or another.

I predict, if driver premitted, the scores should be higher due to GDDR4.
Or, if not, ATI would have proven to us that they know how to bridge 2 chips on 1 card.

It's very pity =(

I kill my P5E64 WS Pro in the first day after it has received, and new I can not buy, it is necessary to wait and use P5E3 WS Pro >_<

I was trying my 3850 256 crossfire with 3870 512 last weekend but the 3dmark06 score that I got is way lower than a single card. I think is like7xxx.
Single 3850 was 94xx and single 3870 was 104xx. Any ideas?

OC that CPU of your's and check the clocks of your GPU's

[mr2sw21]

my 3850 gpu set to 680 and mem was 900 and the 3870 was just stock 700 and 1100.

Nice Work...
