I just have a question... I want to put three 6950 1gb cards in a triple crossfire configuration.

My motherboard will have two x16 pci express slots and one x8 and one x4 and it can support upto quad cards.

So im very new to crossfire setup as this is going to be my 1st pc upgrade in three years.

Can i run sapphire 6950 1gb cards in a triple crossfire configuration?

Is there any review already been done on performance and statistics with these cards in triple configuration?

Do i need to put crossfire bridge cable for all these 3 cards?

Anything else i need to know ?

Thanks a lot!

First up, the CPU would be a bad choice for a serious high-end gaming build. AMD is no longer the king of the hill, as it was back in the Athlon 64 days.

You can get more PCI-E lanes from some Intel chipset boards, and they accept better CPUs also.

Having said all that, triple crossfire is a BAD idea unless you are a serious water cooling type. You will not have sufficient cooling on the cards because they will be pushed up against each other.

So loose the third card, get an i7-2600K and an Asus P8P67 Deluxe board. Pair that with 8GB of DDR3 1.5V RAM like this:

You can get a smaller PSU also:
