ok first of all correct me if im wrong, but sp2 is still in its beta stages no? its not officially released...
i tried to install it about 2 weeks ago (a friend of mine told me it was awesome) and it does look good... but the fact is if its not broke, dont fix it
it for some reason crashed in the middle of the update and my computer fucked up BIG time
i lost a shitload of stuff had to format
anyways... i suggest wait a couple of months till they get it working right
