And the results are goood 
How uneven was it? VERY. And I mean... it took me a good length of time at 240 Grit paper to get rid of all of the plating material.
I had about 3 relatively large patches which refused to budge for ages.
I progressed to a 400 Grit, then a 800 and got a near mirror finish with a 1200 Grit.
I read lots of different guides, and a big thread here a while back about lapping, mirror finishing (or lack thereof required) and techniques. I did not use the figure of 8 technique and just kept it simple with an upwards and downwards fashion turning 90 degress clockwise every 10-15 seconds or so. Same technique for all grits.
So, how much difference did it make? Well initial results show a drop of bewteen 5 and 8 degrees on full load (both cores) before my AS5 has properly cured. So good stuff, idles have gone sub 30 degress and my previous 54-55 Degree C full load on both cores no longer exceeds 49.
Just a mild overclock of 215x11 for 2.3Ghz so hopefully I have room for more before temps become an issue now, just memory holding me back
