Even though I am using a modern and capable laptop (Thinkpad X1 Carbon with 16gb Ram and i7 processor) editing with Camtasia 9 is too slow. Probably because my pc does not have a dedicated GPU chip. I was thinking to use an eGPU. the one that I like most is the Blackmagic eGPU. Other models are those from Sonnet. Would such setup work with Camtasia?

One thing you can try for free first is a RamDisk. With 16 GB of RAM you sure you could free up to 8 GB for a RamDisk.  The two most popular DataRam's and Radeon's Ramdisk which is licensed from DataRam. It's free for RamDisk smaller than 4 GB (4092 MB), so you get to see if it helps without spending a penny.
4GB is plenty to use for all Camtasia's temp files - [Edit], [Preferences], [Advanced] and  then to render to. In that menu you'll also see if Camtasia is using your current graphics card. The great disadvantage of the free version is that updating the imagingefile is done MANUALLY. Forget and you can lose all your work. 

If RamDrive proves effective, pay for it and get the standard version. Ten bucks for up to a 12 GB RamDisk - you can't beat the price. And unlike the free version, the standard version automatically saves an image file to likely your C-Drive.  The image file is managed like a normalized data base, on the fly in 4K chumks, so when you go to turn off the system, it won't slow the shutdown by even a millisecond.
Boot up on other handwill take longer depending on the read speed of the image files' drive. On my older Lenovo a 6GB Ramdrive which uses about 4.5GB, takes an extra 20 or 22 seconds to boot up.

Thanks. That's very interesting. I didn't even know this kind of software exists!

If you try it, please let us know if it worked for you. Also their video is out of date, pre windows 10, so if you need configuration help let me know.
Also for some reason, I set my RamDisk's drive letter as A: and like the fact it nevers displaces a "next available" assignment from windows.
Lastly, if you use a data drive attached to a USB-C port, you may have boot issues with getting the image back to your RamDisk. I don't have the problem, because I don't have a USB-C port!
