Clone it using something like Acronis True Image Home 2012?
As long as you assign the new drive the same letter as the old one so that program's can still find the data etc, it should be fine. TIH 2012 also aligns SSD partitions properly now too.
It depends on the games you have installed, but some of them will work out they've been cloned and ask for re-registration, at least FSX did for me.
