Ok thanks for the tip, Maximus Formula is a hard to find here, can find it from 190€ to 250€.

Im not to aware of what capacitators are and what they do?

I also stumbled apon the ASUS P5E DELUXE, its x48 board. what u think about that? its at an afordable 215€.

Also noticed that all these cards have SupremeFX II Audio Card is this card any good? is it onboard or does it take up one of the PCIe slots?

And you havent answered my other question about eventualy
pairing a HD4870 1Gig with a HD4870X2 ? (which is the most on topic question :p )

Well if u can afford the P5E DELUXE go for it,what is the price difference between RAMPAGE FORMULA and P5E DELUXE ?

The onboard sound card is pretty good i like mine :) it takes on of the PCI-E slots.

I dont recommend u pairing a HD 4870 with HD 4870X2,i recommend u getting 1 HD 4870X2.

i can get the P5E Delux for 214€ and the RAMPAGE FORMULA is 241€.
I didnt want to pass the 200€ margin on my board, i got to see what kind of prices i can get ton the MAXIMUS FORMULA.

The HD4870X2 is way over budget for me at the moment, why dont you recomend puting a 4870 with a 4870X2?

Edit:
Just found a
ASUS MAXIMUS FORMULA for 185€
and a
ASUS RAMPAGE FORMULA for 219€

what do you think is the best deal?

Also i have a doubt about my HD4870 1Gb
I can get a Sapphire for 256€
or
POWERCOLOR OC version for 264€
problem is that im not to familiar with POWERCOLOR but i know the OC version has improved cooling
And i know Sapphire is a good reliable brand

Go for MAXIMUS FORMULA because as i said the difference isnt much and it will save you some bucks.

I dont recommend you putting a HD 4870 with HD 4870X2 because if you want to CrossFire just get 2 same cards in my opinnion.

If the OC verion has better cooling go for it,i have a SAPPHIRE HD 4870X2 and its performing very well.

today i went with a firiend and he bought a Sapphire HD 4870X2, Im jeaolus :p.
But i told him it was a mistake because his LDC is 1680 max resolution, so he wont be taking full advantage of it :p

I have two separate HD4870s which have been in use in separate computers. Now one of the machines is upgraded to a 4870x2, and I want to do Crossfire with the two single 4870s. The problem is that I think I've lost my ribbon cables. I may be able to find one of them, but I think finding both may be impossible.

My question, Will full blown Crossfire work with 1 cable and not have a performance degradation ? I ask because all the crossfire setups I see use 2 cables. Also, if all else fails can I buy the crossfire ribbon cables anywhere?... I have upgraded to an X48 mobo so I will have full x16 crossfire support

Thanks in advance

I will be using Two (single chip) HD4870s... Most of the time I see them, people are using two ribbon cables between the cards. The 4870x2 is in a totally different computer. (it gets confusing talking about two 4870s and the 4870x2 :) )

All the pics I see of the 4870 cards crossfired have 2 ribbon cables... like this:

hey Maziar, remeber you recommended me to buy a MAXIMUS FORMULA Mobo? just like yours. seems ASUS doesnt build it any more :( and the guys from the shop recommend the ASUS P5E WS PRO. what do you think.
Seems all the same as maximus formula just without the good Sound card.

ASUS P5E WS PRO has the solid Capacitors, but doesnt have the SupremeFX II. bothe are the same price, and in same price range is also the ASUS P5E DELUXE.
What to doo what to doo?

P5E DELUXE is a X48 board which i dont recommmend over X38 because the difference isnt much.
Between P5E and P5E WS PRO,both are good,P5E has a little better cooling and P5E WS PRO has solid capacitors.

Ok I'm still confused about x8 and x16 xfire - Will it make a big diff if i get 4850 xfire on x8 link rather than x16? Would the xfire bottleneck my e8400 3.4ghz?
