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?
