[Fudzilla]ATI preparing a revision to the HD3870X2 - Page 3

post #21 of 35
Well, if you already have one, then by the new one and have the old one and the new one in Crossfire! ;D

By then the X2 crossfire/quadfire whatever, should be working better.

Yes. Run a slow card with a faster card in Xfire?

Technically speaking, that is not sound. Wouldn't the faster card need to slow down to match the speed of the slower card... oh wait, Xfire is scalable isn't it? So a fast card can Xfire to a slower card. Ok, perhaps a huge nevermind is in order.

Would that also mean that the 2 cards don't need the same clockspeed?

Uh, they explicitly say that the 3870 and 3850 are compatible... what about that makes you think gddr memory version matters?

It's a real bugger getting DDR4 to fit in DDR3 slots, yeah?

They are indeed compatible. When i ran 2900 Xfire, i had one 512 MB GDDR3 card and one 1 GB GDDR4 card. They ran fine together, just the 1 GB card only showed 512 MB

why would u want to xfire a 3870 and a 3850...

thats like spening all that money on a xfire mobo and only going half way... a half assed xfire job.

I doubt that added 3859 is worth a lousy 10 fps in crysis...

but u guys tend to be more knowledgeable about such things, anyone care to shed some light as to the usefulness of this?

That GDDR4 should have been there from the get go. Kinda makes me think they should have just named it an overclocked 3850X2.

surely a PCIe 2.0 upgrade will help with bandwidth bottlenecks that may be caused by the limitation of the CPU in high resolution gaming.
