The CPU, SSD, and ram should be enough to handle moderate editing. The only weak part is the GPU. The GPU cannot run most games out there. Even a 11 year old GPU (GTX 280) does 100% better (according to UserBenchmark). I suggest you get a better GPU like a GT 1030 if you're on a budget. If you can spend another 100$, then get either a GTX 1050 or 1050 ti. The difference between the 1050 and the 710 is MASSIVE. But on the editing side, I think Camtasia uses most of the CPU instead of the GPU. But if Camtasia mostly uses the GPU, you MUST get a better GPU. Other than that, everything else is fine.

(Right now, I found a 1050 Ti for $150, if you want it, here: https://www.amazon.com/PNY-GeForce-1050-Gaming-Overclocked/dp/B07QZ8MC8K/ref=sr_1_5?keywords=gtx+1050+ti&qid=1567898726&s=gateway&sr=8-5)
