does amount of ram matter with solid state drives?

Try to think of memory storage in 3 stages: CPU>RAM>Hard drive/Solid state Drive.
When you run a program, it's resources are called up from the storage drive and stored in memory so that if you should keep using that program, data can be recalled very quickly rather than having to go back to the storage drive to find it again. The CPU memory or cache is usually only a few MB big and so handles the most needed data to run/process the software you are using. Less needed data is moved down and stored in the RAM (random access memory) where, when it is needed, it is transferred to the CPU to be processed. Now the lowest level but the level with the most space is obviously the Hard drive and now more commonly Solid state drive. Whilst Solid state drives are fast, they're no where near as fast as RAM meaning once you've filled your RAM up, memory will start to be "paged" to the storage drive. Of course with an SSD being faster than a HDD, the computer will be faster but you want to try and minimise the amount of data that has to be paged to the storage drive, this is obviously done by having more RAM.
Short answer; Yes, the amount of RAM is still very important even with an SSD as opposed to a HDD.
