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I was reading a post saying certain drivers aren't any good for 4+ cards however post was pretty outdated.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