Driver and SDK for HD7970

[Metta28]

I currently have 3 7970's on one rig and 2 on another however once my local shop gets the 1x-16x risers in stock again it will be 5 on one rig.

I was reading a post saying certain drivers aren't any good for 4+ cards however post was pretty outdated.

So any up to date suggestions on driver SDK combo for 5 x 7970?

Thanks

Edit: I am running Windows XP SP3

Don't know about the driver issue but make sure that you're using powered extenders for those 7970s.  You can get away running 6 low end 7770s off 1 mobo without additional power, but 5 7970s will burn out the ATX connector on the mobo.  You will need at least 2 or 3 powered extenders.

Thanks for that bit of advice, do you mean something like this http://www.newegg.com/Product/Product.aspx?Item=N82E16812200121?

If not link me to what you do mean.

Sorry the Newegg link came up dead.

I remember a post in the last week talking how to make your own powered extenders, search for it.

Or go here: https://bitcointalk.org/index.php?topic=7216.0

and scroll through - that's like the how to on building a rig.

Here's the link to the Do-it-yourself powered extender:

Basically you want to send more power to the card and not have the card try to pull it from the motherboard - hence the molex cable sticking out on the side.  Some places like cablesaurus sell them premade.
