Just changed the mobo in my rig and did a refresh of Win7 using the upgrade trick and I'm not sure if its as good as a clean install. I went from an H55 mobo to an Asrock P67 Transformer mobo that lets me use my old cpu and while everything seems OK, my SSD writes are lower while the reads are up to sata 6GB speeds but sporadically. The refresh trick is supposed to make the system run like a clean install but I'm not sure if what I'm seeing is right for the new mobo or if should just do a clean install. Any recommendations?
