I realise both systems are over kill but my next computer will have to last 5 years+
Any help from tech guys?

He111 be careful not to compare apples with pears, have a look here:-

Those results are backed up by other reviews (I spent 3 months looking at them before buying my new PC in December).
If you have the money to be thinking 580 you should be comparing it with the 5970 or even wait until the AMD 6990 comes out and gets some reviews. I'm not saying I recommend AMD, in fact I bought Nvidia 570 instead of AMD 6970 for my own reasons, but the 6990 should be pitching at or above the 580 performance.
Essentially the difference between the AMD 58xx and 69xx series is the 68's use lower power and deliver far better tesselation performance (although CoD doesn't use tesselation). The 69xx series will push the 58xx series down in price but at the level you are considering the 58xx series is not the way to go IMHO.
