Had issues not resolved with windows 7 and needed to reformat. Held off reformat till I could afford the new samsung 830 128gb ssd. Being a professional photographer I depend on a fast, stable machine. Taking advantage of my slow season, I am trying to get this machine running smooth. Currently less than halfway through reinstalling software and would like to know if it is worth upgrading the motherboard to sata 3 before I get comfy setting everything up. This machine is used exclusively for photoshop, lightroom, and uploading photos.
