Might be worth just checking you haven't put both PSU cables on a single 20A PSU output rail. If your local to blackpool, I have a spare 1250w PSU you could borrow just to rule it out mate.

A chap on the 7970 thread just pointed out there is a new update out for it, V1.05 I think, and I can confim that on my rig, the stuttering has gone and Xfire scaling is now fixed at long last!
