I'm just after buying a 5970 + core i7 860. But the cpu is overclocked to 3.2ghz

The psu i've gotten is the OCZ ModXStream Pro 700W ATX 2.2.

Would the psu be good enough? On the powercolor site is says the the graphics card needs 650W.

Yes that PSU would suffice...though not one of the best PSUs out there, but are good enough...

Oh really? I was under the impression it was very good :/ 

I'd also be running,

3 fans
2 HDD
1 SSD
4 gigs of gskill @ 1600
DVD drive

If any of that stuff makes a difference.

Corsair TX750 would have been better or a Seasonic 700W PSU.

Is there any stress test to ensure my whole pc works fine with this psu and wont fail.

Would prime 95 do this?

Cheers bud! Would the stability test be sufficient or should I run the Xtreame burning?

Also would 6-7 hours be sufficient time to leave it run?

Well actually even an hour or 2 would suffice IMO...
In real-world scenarios, it is not possible that both the CPU and GPU would be in full stress for a very long time...
Even when gaming, the GPUs are not fully stressed...

o.O Should I run the two tests together? To make sure temp/PSU is ok? Or is that over kill?

^ Well its upto you...but like you said, it might be an overkill... ;)

Nothing outside of a laboratory environment. That's why it's so important, IMHO, to use the highest wattage quality PSU you can afford. The less you stress a PSU the more consistently it performs and the longer it lasts. It's not like a CPU that will be outdated in a year. It's the cheapest insurance policy you'll ever buy for your new rig.
