It doesn't really make much sense to talk about overworking a CPU. They're extremely robust and many applications will run them at 100% 24/7 for their entire lifetime.
A bit of transcoding in between waiting for the DVD drive to read the data isn't a high stress use.
You can talk about 'overwork' in a real time application like rendering a game where a CPU can't keep up, but when transcoding video a faster CPU will run at exactly the same load - it'll just complete the task a bit faster.
In terms of encoding you need to be using the right software. GPU accelerated encoding never really took off as it's only really a major improvement with a top of the line CPU.
Most encoding these days is either done with fixed function hardware (Quicksync in Intel chips, VCE and VCN in AMD and NVENC in nVidia) or CPU only for greater control. For the former to be used your transcoding software has to support the individual technologies.
What sort of time is it taking to transcode a disc currently and how does that compare to the time reading the disc (which is limited by the DVD drive, not the CPU)?
I can't help with second hand prices in the US. Why not look at common places stuff is sold and see what previous items have gone for? |
