Great deal. But for photoshop? A Celoron can barley process Windows itself, why would you use photoshop on it (try the original Celoron, I'm not even sure that thing had a processor in it)? So, I guess you could barley get away for basic internet use, for now, with that laptop. But I recommend looking into a custom PC for photoshop. Any laptop CPUs aren't the same as a desktop one. They use a lot less power (which the cost is low enough that doesn't matter at all, although it does if your running off a battery) but other then that they pretty much cut all the good things out like 3.0GHz+, lots of cache and just features I don't use but they just make my PC's specs look fancy. Same goes for laptop GPUs. Which I would like to mention that with the use of OpenCL
with modern graphics cards you can do amazing photo editing without lag.
