Can someone please explain to me what to look for in a PC.
As I understand, RAM is memory, allowing multiple applications to run.
The processor is how fast it actually does the computation.
Apart from these two factors, what should I be looking out for if I want a PC purely to process calculations, ie no gaming required?
If we compared a 2GHz eight core processor with a 4GHz quad core, all other factors being identical, which would be faster?
Also, what is i3, i5 and i7, 32 bit v 64 bit (obviously 64 bit is better but by how many times)?
On a separate note, if I want a PC to edit HD videos, what's the key element? Graphics card or something else?
