Yes, it is always a question of what is best to take for video editing. The more and complicated transitions and FX you use, the more powerful the computer has to be. If you want to (or have to) be mobile, it's better to take a laptop, but that costs a lot more for the same configuration. My PC is now 1.5 years old, before that I had one for 9 years - it just got a bit tedious at the end, and then there were always problems because of the lack of performance. If you buy something new, it is certainly important to invest in something with a promising future, otherwise you will be back in the queue and dissatisfied again.
