So I am considering upgrading with a 120Gb SSD to compliment my 1Tb HDD. I would like to run my OS, Steam Games, and Photoshop from the SSD. However I do not have the installation disk for windows 7. I have the product key but no disc. So doing a fresh install of windows on the new SSD is probably not going to work without buying it again right? I have read that you can use software like acronis to basically transfer the OS to the new SSD but it seems pretty complicated from what I have read. Are there any step by step how to's on transfering the OS for a noob like me? And can you use the same software to pick and choose software to transfer like photoshop, games etc? Lastly can anyone tell me with any certainty if a 120Gb SDD will be big enough to run windows 7, photoshop and half a dozen newer games?
