Just about any system can edit video, provided there is sufficient RAM. Some of us have been editing video files with systems that long preceded multicore systems.
In general, there are 4 considerations, IMO:
a. Software which will be used
c. CPU model/capabilities
d. Hard drive space to store video files.
Software chosen is strictly user preference...I have 3 programs that I use routinely and I'm easy to please.
Rendering is RAM-intensive...so you want more RAM than the advertised/stated minimum which the software recommends...but you don't need more than is useful. I find that 4GB is sufficient for what I do and my systems and RAM is super cheap these days, IMO.
Up to a point...a faster CPU results in faster processing of video. But that doesn't necessarily mean that you need an 8-core CPU for optimum results. I just use a 2-core CPU and it seems to do the job. I've been trying to convince myself that I need a faster CPU...and it just ain't so:). On the subject of CPUs...I suggest getting an Intel CPU, rather than an AMD CPU for your system...the general consensus is that Intels do better at video than AMD processors. For me, that's not terrifically important...for you, it may be important.
If I were going to buy a system for video today, I suppose that I would get an I5 system, since that would do the job and seemingly outperform all other CPUs other than the I7s.
