Hi guys, a few day ago I was trying to buy me a card AMD 7970 but the seller said me what kind of 7970 I want and said that are ASUS, sapphire and XFX, he said that is the same AMD 7970 but was ensambled by differents companies, then I want to ask you.

Which is better? and also what kind of motherboard will be better If want to use 2 X 7970.

this were my options

ASUS HD 7970 DirectCU II TOP 3GB GDDR5 (HD7970-DC2T-3GD5)
PCI Express x16 3.0, ATI Radeon HD 7970 3072 Мб


Sapphire HD 7970 OC 3GB GDDR5 (11197-03)
PCI Express x16 3.0, ATI Radeon HD 7970 3072 Мб

XFX HD 7970 Black Edition 3GB GDDR5 (FX-797A-TDBC)
PCI Express x16 3.0, ATI Radeon HD 7970 3072 Мб

thnx

why you dont post the clock speeds ? i would always prefere sapphire , but mostly the price is it.

depends on if you want reference or non-reference design.

the asus directcu II is the best non-reference card i've seen. perfect for desktops.

A customer of me use 4 of those https://www.mindfactory.de/product_info.p...10278.html , the aircooling system is very quit and the card have a big oc potential , stock 1ghz , some settings 1.1ghz s+table.

Hey epixoip, we're looking to pick up some new reference 7970s, has anything changed since that thread you posted? Any new reference models to look at, or pretty much the same options?
