I have been using Photoshop CC and Bridge after upgrading from CS5. I have had a lot of problems with PS CC being very slow to react and to load files, also many times I have had to give up and start again as the little coloured wheel is on my screen more than me working in CC. I have not loaded up Lightroom as I have never used it and I load my files from Bridge. I have just started back onto my PS CS5 and it works great, so I may have to cancel my CC subscription as PS is making my whole computer very slow. If you have a soloution then be glad to hear it.
