Personally, i wouldn't use only an SSD for a video editing computer. Using an SSD as a scratch disk will give you a speed boost, but apparently you will drastically shorten its lifespan, since SSDs have write limit. A dual hard drive setup may be a better option. They always say you want to have your scratch disk on a separate drive than the file you are working on. Plus 120gb will fill up fast depending on the video size/quality you work with.
Also, by not using a Nvidia card, you're missing out on GPU acceleration from the CUDA cores, if you care about that kind of thing.
