We talked about novice level.

And what do you understand when saying "serious rendering"?
Do you wand to produce every day a new 2h movie in HD?

If you are on a level you frequently think software like cinelerra is
leaking some features and you don't need to check the manual anymore,
because it can't tell you anything new, and you are preparing every day
several hours of videomaterial, then you are on a level you might think
about a rendering farm.

For anything else a well equipted PC with a CPU like a medium class
CoreI5 can do Full-HD rendering in realtime.
Memory is cheap. What you will need some realy fast HDDs. This is often
the bottleneck. The disks are to slow.
Calculate how much bandwith a Full HD video uncompressed needs. Compare
this with the transferrates of consumer HDDS. Surprise!
The in the CPU integrated GPU is more than powerfull enough. The only
requirement to the GPU when rendering Videos: Should be able to display
it in full resolution.
Normal Video rendering the GPU is not involved in any way. This becomes
only interesting when you are dealing with a lot of digital FX or
creating entire virtual realities......
I guess at least 90% of all Computers used for Video processing are
oversized. The problem is not the PC the broplem exists between chair
and keyboard.....
