Thanks mate, that's good to know. A quad core laptop it is!

[How effectively does Photo use additional cores and dGPUs?]

I apologize if this question has already been asked and answered, but since I intend to buy a new laptop in the next month or so it is important for me to know how effectively Photo can use quad-core CPUs and dedicated GPUs? I'm leaning towards ultrabooks because of their superior mobility. However, if Photo is able to effectively use 4 cores and fast GPUs, I would rather get a beefier laptop, which is less mobile but offers more processing power.    

 

So, does anyone know what's crucial for good performance in Photo? Good single thread performance, additional cores or dedicated GPU?

 

Thanks!
